Good shirts
100% cotton. Yay! And thicker than the normal 100% cotton shirts I have found. Made well. Could do with better designs and colors but overall am happy.

Nice kids shirt
Size: Small, Color: Dark Emerald Green Blue Block Stripe
Having had mixed experiences with Amazon essentials- this one is a winner. Looks like more expensive brands, soft material, vibrant colors after many washes, Fits true to size. Only downside is that the buttons are particularly hard, so small hands need adult assistance.
