I was initially hesitant to even rent a dress ( this was my first time =o] ) but than I just decided I might as well try it rather than just wandering how it would work. I am 5'1" 125/128lbs ; I thought it was going to be too tight on me so I got the size Small and Medium... they were both too big! The small fit and i was comfortable but it was loose ( I could feel it) and I also have like a barely there chest so I was worried about it being too loose up top. I should have gotten the XS but now I know that for next time. I would totally rent another dress again and definitely another one from this same designer. The dress was in great condition and just overall PERFECT. I received so many compliments <3
