This week's wardrobe malfunctions (and close calls) brought us the typical blunders but with some lethal twists. Celebrities stepped out in lingerie-like outfits to brave the summer sun and the usual string of parties and premieres didn't fail to disappoint in the risky wardrobe department either.

Whether it was Jessica Chastain's breezy skirt or Katy Perry's dangerous dress, stars weren't afraid to brave skin-baring ensembles. Check out the slideshow to see our picks for who came closest to a fashion fail.

  • Kat Dennings

    Kat Dennings appeared for the CBS, Showtime and the CW 2012 TCA Summer Tour Party in Beverly Hills on July 29 in an ensemble that confused and amazed us. We were astounded by how her cleavage held itself up in such a way...what kind of bra was she wearing to create such a lift? The young actress looked as if she was about to pop out of her revealing dress but fortunately, she didn't suffer any kind of wardrobe malfunction. (Getty photo)

  • Katy Perry

    Katy Perry stepped out on July 28th in a cowboy-inspired airport outfit, that was not only strangely dark for the pop-star diva, but was also sheer. The singer's bra was visible under her shiny black tank top and we we're glad that she was wearing the proper undergarments. (Fame Flynet photo)

  • Olivia Munn

    The TV personality-turned actress stepped out in New York City on July 28th in what appeared to be a <a href="http://www.huffingtonpost.com/2012/07/28/olivia-munns-top-underwear_n_1713566.html" target="_hplink">silk camisole</a>. Munn looked sexy in a leopard pencil-skirt, red lips and pumps, but we were curious whether or not lingerie has suddenly become acceptable to wear as regular clothing. Either way, Munn looked fab.

  • Lucy Lui

    The actress looked fabulous at the CBS, Showtime and the CW 2012 TCA Summer Tour party on July 29th. Lui stepped out on the red carpet in an edgy LBD with flowered cut-outs, revealing a plunging neckline. Lucy Lui rocked her classic and sexy look, though it had major side-boob potential.

  • Jessica Chastain

    Jessica Chastain had a <a href="http://www.huffingtonpost.com/2012/07/31/jessica-chastain-wardrobe-malfunction-skirt_n_1724622.html?utm_hp_ref=style" target="_hplink">major wardrobe malfunction</a> on the set of her new movie "The Disappearance of Eleanor Rigby" in New York City on July 31st. Unfortunately for the stylish actress, there wasn't much that she could to combat the wind and it blew up her dress, revealing way too much. (Pacific Coast News photo)

  • Katy Perry

    Katy Perry had a very cleavage-ridden week. At a promotion of her film "Katy Perry: Part Of Me 3D" <a href="http://www.huffingtonpost.com/2012/07/31/katy-perry-cleavage-braless-dress-2012_n_1722717.html?utm_hp_ref=style" target="_hplink">in Rio de Janeiro on July 31</a>, Perry donned a bright yellow dress with strategically-placed diamond cut outs going down her torso which acted as a kind of peek-a-boo plunging neckline. The exposure these cut outs created made it virtually impossible for the singer to wear a bra with this dress, but of course, Perry managed to avoid a wardrobe malfunction as she's pretty used to <a href="http://www.huffingtonpost.com/2012/07/12/katy-perry-bra-peppermint-banned_n_1668002.html?utm_hp_ref=katy-perry" target="_hplink">"hazardous" outfits</a>.

  • Heidi Klum

    Heidi Klum stepped out with her youngest daughter Lou Sulola Samuel (adorable!) in NYC on July 28th. The model-turned-entrepreneur was dressed casually in sandals, cozy looking harem pants and a long black sweater. Klum, however, opted to go braless with a black tank, which although comfortable, put on a show. (Pacific Coast News photo)

  • Iliza Shlesinger

    Comedian Iliza Shelsinger stepped onto the red carpet at the CBS, Showtime and the CW TCA Summer Tour party in a sultry, sequined mini-dress. Shelsinger wore black pumps, completing her sexy look which also featured some major cleavage action. We were most concerned about the length of the TV star's dress as it seemed to pull up towards the thigh-area of her legs. (Getty photo)

  • Chloe Sevigny

    Chloe Sevigny looked oddly frumpy while apartment hunting in NYC on July 31st. The actress wore a mini shirt-dress--which looked more like a long, sleeveless t-shirt--with white sneakers and a shoulder purse. Although the star did not suffer a wardrobe malfunction, the dress she wore was so short that if she had to pick something off the floor, it would have been a disaster. (Pacific Coast News photo)

  • Poppy Montgomery

    Poppy Montgomery graced the TCA Summer Tour party's red carpet on July 29th in a dress that looked more like a babydoll than a dress. The Australian TV actress donned a short, white and sheer dress which was sexy but (we think) a little too sexy for the red carpet. We were surprised to see that although the dress was sheer, Montgomery managed to avoid any kind of wardrobe malfunction. (Getty photo)
