2. Katherine Heigl
There’s no denying that Katherine looked amazing in that dress, but clearly it was a little bit too tight...the strap pinged itself off the back of her dress during her acceptance speech, and if it wasn’t for a very attentive host, Billy Bush, she’d have flashed everything. Like a true gent, he held her strap for her so she could finish her speech, and helped her off stage. The lesson? If you’ve had to squeeze yourself in, don’t count on it holding!
