This slip seems to be on the smaller side. I'm 5'5 and 140 lb, and usually size 36 fits me fine. But I decided to return this slip because it was too tight. The fabric has more spandex than in the description, there actually is 27% spandex and not 11%. That makes the slip very-very stretchy, so I could still ware it, but it did not look right. To my taste, the fabric has too much spandex. I prefer the classic silky/sateen feel and flow. I would not recommend this product. There are other ones, better.
