7 Tips For Looking 10 Pounds Thinner In Your Wedding Dress

I can't tell you how many of my clients proclaim that they WILL lose 10 pounds before the big day! Who doesn't want to look fabulous on their wedding day? Well here are some helpful tips just in case your diet plan doesn't work out!

Don't Go Bra-less
Lifting your bust to allow the bodice of your gown to fit properly is critical. Many brides opt out of wearing the proper undergarment because they fear it will be uncomfortable. Specialty bra stores will usually allow you to buy several styles to try on with your wedding gown, allowing you to return the ones you don't choose. If you are a smaller cup size, A or B, then you may wish to have cups sewn into the dress for both support and comfort.

Add a Gorgeous Beaded Belt or Silk Sash to Your Wedding Gown
Belts and sashes are an amazingly simple way to emphasize your waistline. It's important to consider which area of your torso you want to accentuate. Experiment by placing the belt or sash across your natural waistline, under your bust-line or across the dropped waistline. Don't be afraid to play around with this. Once you find the most flattering spot, your seamstress can attach it for you.

Work Out Those Arms
Even if you hate to exercise, try some triceps and bicep curls for about eight weeks up until your wedding day. Most wedding gowns are strapless or sleeveless so if your arms are "cut", you're sure to look amazing!

Choose a Gown with a Corset
The corset back is back! Many wedding gown designers have incorporated the corset into their dress designs realizing that women still want to feature a tiny waistline. These corset designs will allow you to make the dress as snug as you like and make your waist as small as it can be!

Wear a heel...any heel
Wearing a heel on your wedding day can make a big difference. But what if your fiancé isn't that tall? I recommend still wearing a small heel, even if the heel is only a 1/4 of an inch, it will give you a little height, your posture will improve and you'll look taller and thinner.

Consider a "Fit and Flair" gown
It used to be that the A-line gown was the most flattering style on many body types but the fairly new "Fit and Flair" silhouette has become extremely popular. This silhouette softly drops down over the hips and gradually begins to open at mid-thigh. It is stunning and figure flattering.

Get Good Alterations
I can't stress enough how important professional alterations are. It is worth every penny to have an expert seamstress fit your gown the way it is intended to be worn. When the fit is right, you'll look and feel right!
