While celeb outfits were supposed to take centre stage at Sunday night's Emmys, it became apparent to us — after a few A-list entrees onto the red carpet — that squoobs, breasts and cleavage were set to steal the show.

From Kat Dennings' squished chest to Sofia Vergara's droopy assets, something was missing from almost every Hollywood starlet's award-night wardrobe: A bra.

Even when a celeb wore one, like Zooey Deschanel, the undergarment malfunctioned. (Deschanel had to have her bra cut off after she and her publicist noticed it poking out from under her strapless dress.)

Now, we know finding the right bra to fit and lift a bod is a tough job. But if you're a famous face in Tinseltown (especially if you're walking a red carpet), you likely have a stylist and multiple wardrobe experts to help you out. So what gives?

One expert believes people may be relying a wee bit too heavily on bra adhesives and glue. Alicia Vianga, a HuffPost blogger and bra fitting expert, notes these concoctions won't help lift breasts — they simply ensure an outfit won't slip past the nipple. "Unless absolutely necessary, be sure to wear a bra. It will give you lift and shape your outfit," Vianga writes.

She also notes there are ways to prevent cleavage spillage when you're wearing the wrong bra for a specific ensemble: "Make sure the cup size is the right size! A cup that's too small will lead to bulges, spilling and of course popping out. A cup size that is too big will lead to gaping and a lack of support. Wardrobe malfunctions can be avoided with a good bra fitting."

How can you prevent boob mishaps like the ones we saw at the Emmys? Here are some suggestions, from a recent story on The HuffPost U.K., that will help you tell if your undergarment is ill-fitting.

-- [If] there are red marks under the shoulder straps or indentation marks on the shoulders. The marks indicate that the back of the bra is too big and that the ribcage is not supporting the weight of the breasts
-- The back of the bra should be horizontal from the front of the chest rather than rising up at the back
-- The front of the bra should fit the sternum firmly
-- If you have flesh spilling out from sides or top of the bra cup (known as the quadraboob) — the bra cup should snugly enclose the breast
-- If the wires dig in, the cup size is too small

  • Breast Cancer

    Unsurprisingly, the study found that a history of breast cancer has a significant impact on how a woman's breasts look later in life. Breast cancer impacts breasts in three ways: 1. Women with breast cancer have more scarring on their breasts than women who never had breast cancer. 2. Cancer survivors have greater <a href="http://en.wikipedia.org/wiki/Ptosis_(breasts)" target="_hplink">glandular ptosis</a>, otherwise known as drooping or saggy breasts. 3. Women who survived breast cancer are also more likely to have asymmetrical breasts.

  • Cigarette Smoking

    Smoking cigarettes also negatively impacts women's breasts over time, the study showed. Cigarettes decrease breasts' skin quality, breast projection (meaning the distance that one's breasts extend forward from the chest). Women who smoked cigarettes were also found to have less attractive breast size and less attractive areolar size (the skin surrounding the nipple).

  • Hormone Replacement Therapy

    Hormone replacement therapy (HRT), a treatment generally used to decrease the symptoms of menopause, was found to have positive effects on breast attractiveness. Not only did women who went through HRT have breasts that looked younger than those that didn't undergo the treatment, but they also had more attractive breast size, shape and areolas. Women who underwent HRT were also found to have better breast projection (perkiness) and fewer patches of darkened skin on their breasts. This apparent benefit of HRT notwithstanding, researchers and physicians continue to <a href="http://www.myhealthnewsdaily.com/1227-5-experts-hormone-replacement-therapy-safe.html" target="_hplink">debate the safety of HRT</a>. Studies have found that some kinds of HRT may increase <a href="http://www.myhealthnewsdaily.com/485-hormone-therapy-increases-ovarian-cancer-risk.html" target="_hplink">risk of ovarian cancer</a> and <a href="http://www.cancer.org/Cancer/CancerCauses/OtherCarcinogens/MedicalTreatments/menopausal-hormone-replacement-therapy-and-cancer-risk" target="_hplink">breast cancer</a>, while other types of HRT may <a href="http://www.myhealthnewsdaily.com/645-estrogen-hormone-replacement-therapy-reduces-breast-cancer.html" target="_hplink">decrease risk of certain cancers.</a>

  • Daily Moisturizing

    Women who moisturized their skin daily were found to have significantly fewer wrinkles on their breasts than those who did not. Moisturizing was also associated with fewer stretch marks and dark patches on the skin. (Anyone else reaching for their bottle of moisturizer right now?)
