Wearing a Vera Wang wedding gown is a dream for many brides, but how exactly does Vera come up with those dreamy designs?

On Tuesday, the bridal gown designer sat down with Vogue and revealed insights into her design process.

Wang says that she gets inspiration from everything from ready-to-wear to underwear, but it ultimately depends on what she's feeling. Her black wedding dress collection "started because we based the collection on underwear," she told the magazine.

But Wang also takes the wedding venue and theme -- even the number of people attending -- into consideration when designing a custom dress.

"Is it 1,000 people, like an Asian wedding, or are there 30 at a restaurant downtown in New York, you know? So, that all relates into it as well. I like to constantly push myself further but it’s also about the realities of a wedding," she told Vogue.

Vera Wang wedding gowns are popular among celebrities, but she also has a line for David's Bridal for brides with a less-than-celebrity-caliber budget. Click through the slideshow below to get some inspiration from these 15 spring 2013 wedding dresses -- including one red-hot Vera Wang dress.

  • Angel Sanchez

    Before this glossy, unconventionally glamorous ball gown even made it to end of the runway, applause erupted throughout the room. It was just that breathtaking—and not just to the seated onlookers at Angel Sanchez's Spring 2013 show. "The instant photos of this dress popped up on Tumblr, I totally fell for it," says our Web Producer, Allison Bean. "Geometric acetate appliqués decorate the bodice and skirt, which give the gown a futuristic-glam feel. Plus, the embellishments keep the frothy tulle skirt from feeling too princess-y."<br><br><em>Style N103, $11,440, Angel Sanchez</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=angelsanchez?mbid=synd_huffpo" target="blank">See more Angel Sanchez wedding dresses</a>

  • Vera Wang

    "Color was the statement of the Spring 2013 season," says Assistant Editor Phillip B. Crook, "and no show was louder than Vera Wang's crimson-hued collection." While the boundary-pushing designer offered looks in a variety of silhouettes, "this mermaid gown plays with texture in a way that's even more interesting to me than the boldness of the color. I love how the tiny asymmetrical tiers flow down the bodice and explode into a frenzy of folds on the skirt."<br><br><em>Style 111013, $12,500, Vera Wang</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=verawang?mbid=synd_huffpo" target="blank">See more Vera Wang wedding dresses</a>

  • Christos

    Known for her contemporary take on girl-next-door femininity, the Christos bride felt fresher than ever in this trellis point d'esprit design. "The flutter sleeves on this gown are so sweet and delicate," says Web Editor Anne-Marie Scali, "and the faint hint of pattern on the skirt reminds me of cascading waves. So romantic."<br><br><em>Meadow, $4,800, Christos</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=christos?mbid=synd_huffpo" target="blank">See more Christos wedding dresses</a>

  • Elizabeth Fillmore

    Laser-cut lace has been all the rage of late among both bridal and ready-to-wear designers, but Elizabeth Fillmore reinvented the trend by laser-cutting satin to look like lace. "This dress was originally fully lined, but Elizabeth told us she didn't really fall in love with the gown until she removed the lining from the skirt," recalls Phillip. "Of course, that's why I love it, too. It's the sort of dress that only gets better the closer you look."<br><br>Evie, $5,170, Elizabeth Fillmore<br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=elizabethfillmore?mbid=synd_huffpo" target="blank">See more Elizabeth Fillmore wedding dresses</a>

  • Reem Acra

    "This dress is perfect for a bride who doesn't plan on leaving the dance floor but also doesn't want to bother with a time-consuming costume change," notes Associate Editor Alyssa Wells, recalling the growing popularity of convertible gowns. "The billowing tulle skirt is gorgeous going down the aisle and then can be removed, giving way to a short, sparkly look."<br><br><em>Mini Glamour, $3,500, Reem Acra</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=reemacra" target="blank">See more Reem Acra wedding dresses</a>

  • Douglas Hannant

    "After seeing a sketch of this floral-printed dress, I think we all knew it would be one of the big, dramatic moments of Bridal Fashion Week," says Phillip of Douglas Hannant's strapless jacquard gown. "And it was—although any bride who wears will need to be pretty dramatic herself."<br><br><em>Style SGG 97512, $15,400, Douglas Hannant</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=douglas_hannant?mbid=synd_huffpo" target="blank">See more Douglas Hannant wedding dresses</a>

  • Jenny Packham

    "What bohemian bride wouldn't want to wear this?" asks our Community Manager Gray MacDonald of Jenny Packham's softly elegant gown, which the designer herself called a favorite in the collection. "The off-white beaded lace is gorgeous, especially over the sheer sleeves and along the back." Of course, going the boho route doesn't mean you have to sacrifice on sex appeal. "I love how the neckline showcases the décolletage," Gray adds.<br><br><em>Azalea, $6,800, Jenny Packham</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/vendor/results?designer=jennypackham?mbid=synd_huffpo" target="blank">See more Jenny Packham wedding dresses</a>

  • Amsale

    Every season needs its signature short dress, which for Spring 2013 comes courtesy of designer Amsale Aberra. "Is anyone else getting a note of nautical from this one-shoulder dress?" asks Phillip. "Because I totally see some knotted jewelry and a blue-and-white shoe happening here. Bring on the summer yacht club weddings."<br><br><em>Darby, $1,200, Amsale</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=amsale?mbid=synd_huffpo" target="blank">See more Amsale wedding dresses</a>

  • Anne Bowen

    If you loved the metallic-blush gala gown Duchess Kate debuted a few months after her royal wedding, you'll love this bridal version from Anne Bowen—so long as you don't harbor your own princess fantasies. "Brides looking for a 'red carpet' rather than a 'Cinderella' moment should definitely consider this dramatic sheath," advises Allison. "This stunner was one of my favorite gowns this season—the sequined fabric has an almost liquid-like quality to it."<br><br><em>Gilded, $8,560, Anne Bowen</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=annebowen?mbid=synd_huffpo" target="blank">See more Anne Bowen wedding dresses</a>

  • Rafael Cennamo

    Rafael Cennamo debuted into bridal with a Spring 2013 collection that channeled the same fashion-forward aesthetic regarded in the Venezuelan designer's eveningwear. "I think this is a line we'll be hearing a lot more from," says Phillip. "This pink, off-the-shoulder lapel gown is so unlike anything else we've seen. There's an edgy, angular approach to soft shapes there that offers an exciting alternative to the traditional gown."<br><br>Style S13-B510, $3,800, Rafael Cennamo<br><br><a href="http://www.brides.com/wedding-dresses-style/bridal-runway-shows/2012/04/new-rafael-cennamo-wedding-dresses-spring-2013#slide=1?mbid=synd_huffpo" target="blank">See more Rafael Cennamo wedding dresses</a>

  • Oscar de la Renta

    While Oscar de la Renta's latest collection splashed the runway in vibrant tones of blue and red, color was just one message culled from the iconic designer's creations for Spring 2013, which also offered quieter, more nuanced statements crafted in taffeta and tulle. "I am obsessed with the neckline on this silk-faille sweetheart gown," confesses Anne-Marie. "The perfectly placed line of bows sailing down the bodice only adds to the appeal."<br><br>Style 44N33, $7,990, Oscar de la Renta<br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=oscardelarenta?mbid=synd_huffpo" target="blank">See more Oscar de la Renta wedding dresses</a>

  • Marchesa

    Somehow, the collections from Marchesa consistently offer a dynamic combo of romance and drama—never too little or too much of either. "This graceful sheath has just the right amount of sparkle," says Alyssa. "Its clean lines draw your eye straight to the intricately beaded neckline, which beautifully frames the face, while a romantic train adds volume without overpowering the dress."<br><br>Pearl, price upon request, Marchesa<br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=marchesa?mbid=synd_huffpo" target="blank">See more Marchesa wedding dresses</a>

  • Carolina Herrera

    "With the hat, without the hat—this dress is just cool," says Phillip, describing Carolina Herrera's double-breasted trench design, which features ivory silk-faille-covered buttons and pockets in the skirt. "But I say with the hat. Give me a French colonial moment any day."<br><br><em>Isolde, $5,990, Carolina Herrera</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=carolinaherrera" target="blank">See more Carolina Herrera wedding dresses</a>

  • Kenneth Pool

    Sometimes when you know, you just know. "I'm in love with this dress!" says Gray, revealing a penchant for Kenneth Pool's slinky beaded gowns. "It's delicate and detailed but holds a certain simplicity that I think is important for a bride. And, boy, does it fit like a glove!"<br><br><em>Lucienne, $9,300, Kenneth Pool</em><br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=kennethpool?mbid=synd_huffpo" target="blank">See more Kenneth Pool wedding dresses</a>

  • Monique Lhuillier

    "How do you make a bride even more radiant than she already is?" says Phillip. "By dusting her dress in flecks of gold." Monique Lhuillier's tulle A-line gown sets a new standard with a cap-sleeve illusion neckline over a sweetheart bodice embroidered with gilded appliqués. "If you look at the end of the rainbow, I'm pretty sure you'll find a Monique bride," he adds.<br><br>Champagne, gown, $14,000, and belt, $1,840, both Monique Lhuillier<br><br><a href="http://www.brides.com/wedding-dresses-style/wedding-dresses/gallery/dresses/runway/results?designer=moniquelhuillier?mbid=synd_huffpo" target="blank">See more Monique Lhuillier wedding dresses</a>
