I wanted to love this underwear but I just can't. I'm 5 feet 1 inch and I weigh 130lbs. I wear a size 4-6 in pants. These underwear are so tight and uncomfortable and I bought mediums. Even if I bought larger I think they would still be too tight. Their advertising about being the best underwear is so not true. I was going to buy their bras but I am so disappointed in their underwear, I won't do it. Live and learn.
