I usually wear a 31/12 in jeans and Large in leggings and dresses, but I ordered a medium after reading the size chart and looking at the picture. I'm glad I did because a large would've been too baggy. I might even try small in a different color just to see if I like the fit better (I like it snug). The lil tube top was too little and too loose at the same time. It gives no support and isn't really tight enough for me to feel comfortable dancing or even lifting my hands too high too fast. On the same token, it doesn't really cover all of my boobies (38D). It's not enough material to wear a strapless bra without it being noticed, so I'd probably have to take it in some, and wear boob tape to lift. However, i see myself wearing either a swimsuit top with it or a better fitting tube top or crop top. Either way, I still like it.
