Seam free and it's best to get one size up from what you usually get so they sit flat and don't cut into your skin
Yes - One size up! My little sister taught me this. I was wondering why all her undies were size 12's when she's an 8...
A loose g-string would be my choice, You can get some seam-free ones that have a wide/flat waist band that shouldn't show through a dress if it's loose enough.
I can remember about 10 years ago when I used to go clubbing I wouldn't wear any undies! I used to wear a skin-tight vinyl skirt that showed everything so it was easier to not wear any! (it was knee length, so no chance of flashing any pink bits....all about the outside silouette being smooth)
