Great style just runs a bit on the small side but I believe they are supposed to fit super snug. My daughter doesn't like it super tight so we ordered 2 sizes larger than she usually wears.

I got this for my 5 year old who has another O'Neill surf shirt in the same size but not the Skins style (the other one is the 24/7 mesh, looser style). Skins is much tighter, which is fine, but the length in torso is also shorter, which is a problem as every time my son bends over half his back is exposed. I kept it because I needed it for a trip and didn't have time to find another long-sleeved rashguard but wouldn't order it again. It's great for in the water, but not for playing on the sand or bending. (It did work okay tucked into his shorts and tied using the board short attachment, but he doesn't like it that way.)

Good quality, but way too small! My son is 6, and I ordered a 8, and it was so tight it was painful to put on and take off. Of course he refused to wear, and I asked for a refund. Emailed with refund method never received, I checked all messages in Junk box. So spent all these money and had to give to someone younger. I am not happy at all. Size chart incorrect.
