Here are some reviews from the web for this t-shirt:
★★★★★ these shirts run slim / long. XS says 3/4 and S says 6x - my daughter is a 5T and wears the small pretty comfortably, and it's not too tight. great color selection, soft & stretchy.
★★★★★ I wanted a true girls cut T-shirt, not a boxy unisex sized shirt. These are exactly what I was looking for! The sizing is what I expected and the large (10-12) I found to be true to size compared to other girls cut shirts.
★★★★★ Absolutely love these shirts. Very soft and form fitted. They do run small but to my understanding that's the fit of the shirt so if you don't like snug fit order bigger size however they are some wonderful shirts to work with when making a tutu outfit or girly shirt.
★★★★☆ I bought these shirts for my 6 and 4 year old daughters. The arms and bodies of the shirts fit great but the shirts are very long on my kids. I would not want to size down at all because then the bodies of the shirts would be too tight but the shirts go completely past their butts. We make them work and wear them with leggings.
Shirts are bright, true colors and well made. Ours have been washed a few times and still looking great.
★★★★★ Used this shirt for my daughter's birthday shirt and it fit her perfectly! She absolutely loved it. My daughter is 8 but is a little in the shorter size so the medium was just a tad long, but it would probably for an average 8 year old just right.
★★★★☆ I used these shirts for my daughter for our trip to Disneyland. They ran slightly smaller than I was expecting, but nothing drastic. The color is great and they wash very well! Would definitely purchase again!
