Gift for granddaughter
Size: Large, Color: Mauve/Butterflies
My granddaughter likes these tops. They are sturdy, comfortable and soft. She loves the ruffles on the shoulder. They were reasonably priced and I feel they will last. Look good after a number of washes.

Shrank after one wash
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

Great addition to wardrobe but size up is likely needed.
Size: Large, Color: Navy/French Stripe
Why did you pick this product vs others?:
These are super cute, but you may want to size up at least 1 size as they are more of a fitted style and fabric.
