This is a WASK tank top. It's made of a soft, double-gauze-like fabric that's easy to move in and absorbs sweat well. It's unisex, so it's cute on both boys and girls. My child wore this when they were about 2-3 years old. It was fun choosing clothes to wear every day, so I bought a lot. I bought too many and they didn't wear them much before outgrowing them, so there are many clean items. They're all still wearable. Kids this age are always moving around, sweating, and getting dirty, so you can never have too many children's clothes, right? It's also recommended to GET them for next season. I was doing matching outfits with siblings, so I have many different sizes of the same design listed separately. You can only dress them in matching clothes when they're small, and they outgrow them quickly, so why not get them USED? Please take a look at my other listings too. WASK stands for "WEE AGED SAUCY KID". This is a design brand with designs that are as good as adult clothes. This is a cool product from WASK. BEBE products have sturdy fabric and sewing, so they're still wearable! I liked American casual style, so I was hooked on WASK and bought a lot. I will be listing more items from now on. As expected from WASK, it has a stylish USED vintage design and elaborate construction. The fabric is sturdy, so I liked wearing it, but it's still wearable. The listed items have been home-cleaned and folded in the closet. There are fold wrinkles. I try to check carefully, but there may be small stains or loose threads that I miss. Please take a good look at the images and ask any questions in the comments. Please purchase only if you understand that these are USED items worn by a boy and are okay with that. I will upload detailed measurements later. Please comment if you are in a hurry. You can wear it right away or buy it for next season! And when they outgrow it, sell it on Mercari (*^^*) DENIM&DUNGAREE, VOLCOM, WASK, DD, American casual, Oshare Honpo, Streetwear items, adidas, Lime Inc, CUBESUGER, Heartmarket, 45rpm, Inc, Arnis Niko and products are scheduled to be listed.
