These are great for a basic top to wear with jeans, shorts, capris or our WONDERFUL beach pants.  These are 100% Combed Cotton, therefore it makes for a little "thicker" tee, so it has great coverage and even the white doesn't "show all".  It has a "ribbed" texture to the material.  They have done a little more detail around the v-neck and the sleeves so it's not "just" a tee shirt.

I say to pop up a size unless you like more of a fitted top.
