I normally wear a US Large. I'm 5'9 and 190 lbs. I bought this shirt for my office job. I like that it's low cut, but not innappropriately. The shirt isn't see through at all and goes down about 3 inches past my belt line. The sleeves fit nice and loose, which helps because I have bigger arms. I do have a bit of a tummy, and this is snug fitting in the middle area, so I would have gotten a size up just based on that. Otherwise, I'm still happy and will still wear it!The shirt is a pretty style however it it extremely long, I am 5'2 and it comes to mid thigh on me, also it is not a bright white, more of a dingy greyish white.This shirt clings to every roll. Cute style for ladies with low to average BMI! I sent it back.Too small, returned it.Love the color and the fit.Nice top but definately size up, snug fitting.It is a cute shirt and color. Nice material. Problem is the shoulders are too wide and the hem is too tight for a proper fit. ReturningI often regret buying my clothes online but this top fits nice
