UA excellent quality tight fit...

This item is very tight-fitting. I use small so I ordered it small despite some reviews that stated they run a size small. Well this is a compression t-shirt so it is very tight. I am 5'6" and weigh about 135 lbs or 63 kgs. I have an athletic body tyoe. This does feel real tight. I had difficulty getting it through my head but once through it felt really well. It does stick to you like a second skin so every single detail of your body will be contoured. I use this for cycling and it works perfectly, keeping sweat away. I think the tight fit looks awesome, but if you are too much of a body image self conscious person that wants to hide it then this is not for you.
