Long-sleeve rash guard in leopard

I purchased this rash guard together with the U-front bandeau bikini top and bikini bottom so I can make a change for the top. It is now winter in Hanoi, so I can wear this to keep me warm at the swimming pool. To me, its fit is true to size. The rash guard material is a little thinner than the ones from previous years. I am happy to add more pieces to my Jcrew swimming collection.

I have several of these long-sleeved rash guards from Jcrew, all size Small. But this one I'll be exchanging for a Medium. It's slightly slimmer than my other ones and so the leopard design looks a bit stretched out on the bust. Otherwise it's beautiful, very soft, and comfortable! The brown color is a rich, elegant shade. Love it! I'm a size 6 in JCrew's slim fit perfect shirt for reference.
