I love this jumpsuit. Wore this to a concert & it was perfect. The material is not thin-however it will show your underwear line. I took the strings out (after reading a few reviews) & it still looked great. Definitely will order from this company again. I'm 5'5 around 158 lbs. I don't have the typical hourglass shape but this jumpsuit still looked great. I got a large (my thighs & tummy).
