Not so fabulous arms

If you're trying to hide a little underarm jiggle, a sleeve that comes farther down your arm is going to be more flattering. And, of course, make sure the sleeve fits -- if it's tight, it'll just bring attention to that area. Something like this Old Navy Shirtdress Belted Shirtdress, $29.50, is a good option because the fabric holds its own shape, so the sleeves won't be clinging to your arms.
