I wanted to love these but they shrank in the washer after one wear. Now they are above my daughters wrist, too small. They do feel good, and have a nice thickness. From initial unpackaging I expected we’d have these in rotation for a while. Looks and feels like a quality buy, until washing. I’ll be saving them for a younger child but my intention was for the oldest. I’ve been trying out the Amazon Essentials brand clothing for kids. Seems to be hit or miss, haven’t come across anything I absolutely love.

Good Quality

Size: Small, Color: Mauve/Butterflies

Beautiful tops. Material is good quality. Fit is a little small but still fits well. All in all it is excellent quality for your money.

Cute staple shirts, run small

Size: 2T, Color: Black/Ivory

Cute shirt with soft material, good quality for price. However, they run small. For reference, my daughter is typically in 18m- I bought size 2T in these shirts and they are still short on her. They raise up on her belly if worn with regular pants. For this reason, I use them mostly under overalls, vests, dresses, etc
