I plan on using these shirts for a bachelorette party! I will be using siser on them, according to other reviews that has worked out nicely (I have not yet made them). The colors I ordered were the hot pink & white and both look great. They are super soft which is great! I would say they are pretty true to size. I normally wear a large in tops (5'4 175lbs, 38D) so I ordered a large and it fits..very fitted. If you don't want super fitted I would order a size up.
