    • Perfect comfy shirt for boys!
Size: 3T Color: Blaze Orange
Review Image by Meghan
I bought three of these shirts and I am so glad that I did! They are so cute! And so soft! These are definitely not see-through and my children loved them even when it was 90° and humid! They do wrinkle a little more than I expected, but I also let them sit in the laundry basket for a day before I hung them, so that’s probably on me! I really like the thickness of the fabric! I think it’s absolutely perfect for a summer shirt! Just heavy enough to not be transparent in any way! These are so simple! You can dress them up or down! I could put my kids in khakis, denim jeans, or denim shorts, and it would match! I will likely buy more! The sizes are perfect, but for reference, the blue is a 6, the red is a 4, and the orange is a 3T. ... show more
