I normally wear a size XL or size 14 in most T-shirts/Blouses. I read the reviews and figured I should get the largest size (4x). I bought the grey color and it Fits good (not too tight not to loose)iTS REALLY CUTE! I just ordered the black one today. Its a good price for a cute Tee 

Update: Got the black one in the same size and it is way too big
