I like the color and material of this sun shirt, but the sizing is very small; I ordered a boys' and a girls' size 12 for my b/g twins. I'm including a picture to show the discrepancy between boys' size 12 and girls' size 12. My daughter is thin, only 75 lbs at 12.5 years old, so this shirt should not be tight and show her stomach. It looks like a size 8-10 to me, so be careful and size up if you order the girls. I ended up returning this and ordering a boys' shirt for her to make sure it fit and did not sexualize her.
