I read the other reviews and by pictures and what was stated, I went with a medium. Im 55 110lbs but vary due to my chronic illness from 102-116lbs. Clothes shopping is an annoying and frequent thing for me. Well I was scared to do small and it obviously be too small so went with the next size up because there is a 55 115lbs chick that said it was perfect and thats in my range. Guys, if you're ever between 100-110, do not buy the medium. They eat me and I even had shorts on under them! I don't even have to unbutton, they just slide on/off like pull-ups. I have no butt so maybe thats why it was so different too because the girl I mentioned had more of a donk than me. So if you're the cliche white girl butt and between 100-110 lbs definitely go with the small even if your freaked out. We can always send them back which is what Im doing; Ill provide pictures for yall to see. Other than Size, I think they're pretty awesome; 4 stars mostly due to fit. I think they're an okay price for the quality
