Underwear Oops

Bra straps showing? Muffin top? Visible panty lines or even worse, visible panties?
Sigourney Weaver's unexpected exposure on "The View" this week could have been avoided by keeping her legs clamped together, but many other celebrities have learned the hard way that even a picture perfect outfit can be ruined by the wrong undergarments. But these common "undies oops" are easily avoided. Melissa Foss shows what you can learn from these stars' foundation faux pas.

The "SAG" awards - Get A Little Support For Your Friends
No woman, actress or otherwise, dreams about winning a "sag." See Drew Barrymore, who, inexplicably, decided to go au naturale for an awards show (the Golden Globes, actually. Insert joke here).

Imagine the silhouette she could have cut if only she was wearing the right bra. "This is an easy problem to solve as any under-wired support bra -- whether plunge, tee shirt or balcony style -- will create lift and support." advises Francesca Luther, Creative Director for lingerie store Myla

VPL- Visible Panty Lines
Alert: Always check your rear view in a 3-way-mirror! Even a skinny minnie, fashion-forward celeb like Teri Hatcher isn't immune. While thongs have a reputation for curtailing this issue, it's actually the under-rated boy shorts that prevent a VPL catastrophe.

"Boy shorts were invented to solve this problem," says Heide Kennedy, stylist for the chic sample sale site, Savvy (www.theSavvy.com). Choose a pair that are smooth, not lacy, to sport under workout gear, skirts, pants, and even jeans. You think you look good arriving? Now you know you look great leaving too.

Too-Much-Info Undies
It's no secret that Paris has longstanding undie issues. Here's some advice: When it comes to low-rise jeans, a little mystery goes a long way.

To avoid the low-rise "oops" (so you can lean over without fear), try the go-to undies Hollywood loves. They're designed to sit lower on the hip and have a 3.5 inch rise (which covers the important bits, but not much more). Cameron Diaz is a fan.

The Roll No One Wants To Serve
A muffin top is the result of a too tight pair of pants meeting a not too taut torso, and the condition is exacerbated when your top is also tight, or not quite long enough. It's a fashion foul that Kelly Clarkson has been called on repeatedly.

The goal: To under-emphasize your muffin and make you feel comfortable even in today's trendy shorter jackets. Check out Yummie Tummie tank tops. Wear them under fitted tops - they won't cling, they're extra long to conceal trouble spots, and they also have a subtle built-in spandex tummy panel. And they're now available in plus sizes!

The Peek-A-Boo Bra
Gwen Stefani (here with KIngston) can get away with showing off her funky leopard bra underneath a top that has tiny little ties for straps but back here in the real world, bra baring tops -- no matter how cute -- are better saved for hanging out in the backyard.
