Neen to the rescue gal pals o'mine. I have two fabulous suggestions:
Under Armour Women's Mesh Boy shorts. Hand to God girlies, these do not ride up, panty lines are non-existent and are extremely comfortable. And, if I do say so myself, they look pretty smokin' when they're on. In fact, while the product description doesn't claim it, I think these little darlings give my tush a smidge of a lift. Yep, I said it! Word of warning: They are low rise, so if you're jammin' on the Oreos, you may want to stay away from these for a day or two.
Skinny Britches by Spanx: These are not wintertime Spanx girls. The lightweight yet suck you in material is perfect for summer. They smooth you out under fitted dresses and are quite comfy. I wore a pair recently and truly forgot I had them on. I plan to buy them in bulk, as most of you know I love me some summah-time dresses.
