I bought this to wear over my swimsuit in the gym pool. I have not tried it on yet but it looks just like the picture. In terms of loose... I am a 57 year old woman size 12 -- I thought extra large would be really loose (hanging loose is what I wanted) but this is the "extra large" size of a teenager, not a grown woman. It will fit fine and snug (without being tightly stretched) -- but not loose. However, if you are looking for something that fits just a little looser than a regular rashguard with a neck that is not too tight, this is perfect. It is made of a very stretchy and nice fabric. You could probably wear this even if you're a much larger size. Also, it would be nicer if it didn't have the manufacturer's name emblazoned across the front. I really hate to pay top dollar for something and then pay to advertise for the manufacturer (they should pay me to wear it! - lol), but I knew when I bought it that the name would show on the front. Otherwise, it is made well, the price is right and the color will match everything. It will work fine for my purposes.
