For comparative purposes: I'm 4'9", around 136 pounds, and my measurements are: 36.42, 30.71, and 36.46 inches.
Anyway, so the straps are very loose on me. This skirt might crafted for taller people, though, so I was expecting it. I wish they were adjustable, but I can just fix them myself.
The skirt fits me well, honestly. I was expecting it to be a little too tight, but no. I didn't have issues putting it on and taking it off. I highly recommend wearing a t-shirt beneath it, since it does squeeze nonetheless. Might make other shirts look a bit strange.
The skirt is quite sheer and conforms to your body, since it's chiffon. The pants underneath, though, save it. If the pants weren't there, you'd have to layer it yourself with some pants or leggings/tights.
Honestly, it's really good quality. Highly recommended.
