I generally wear a small in most workout tops but like a looser fit for my crop tops. So I opted for a medium and it was perfect! That being said, if you want a true to size fit, stick with your normal size. A lot of people said size up, but i found this top was right on the money on the size chart depending on personal preference regarding fit. The colors are vibrant and it was super comfortable for activity. For reference, I do have a longer torso than some, so it may hit you lower on your belly depending on your body type.
If you like short crop tops this is the best one. It is super soft, so I have bought it in multiple colors.
