I can agree wholeheartedly that the whipped A to is made of incredibly soft fabric. It's very thin, and VERY stretchy. Definitely no shaping going on- but who cares when you're wearing something so comfortable! As for sizing, I'm curvy (I'm 5'2", 135 lbs, and a size 32D). I have ordered a size M in panties and size S in tanks/tees for almost 10 years. This was my first time ordering from Negative, so I ordered my normal size- and I was shocked to find it was huge on me! I had read a few reviews that recommended short women should size down, and it's great advice I wish I'd followed. The tank dips really low on me, almost as low as my nipples. I washed and dried it on high heat, but the fabric is such high quality, that it didn't shrink a bit. But I love it so much, I'm going to give it another try, just in a XS next time.
