CONSIDER THE CHILD'S BODY TYPE AND THE CUT OR VERSATILITY OF A PARTICULAR STYLE
Appaman runs true to size, but it’s based on a narrow cut. Also, the sizes are based on a garment having a fitted look. This means, if your child is on the slim or lean side, they will likely wear their usual size and it will fit comfortably. If your child is not the long and lean type, and you are choosing something that’s slim-fitted like a "skinny fit" trouser, you might want to size up to allow for a more generous fit. This is less important if you’re ordering a more forgiving style like slouchy sweats or an elastic waist skirt.

Keep in mind:

• Many of our woven pants and trousers have a hidden elastic band in the waist, so you can always cinch the waist smaller.
• For some jackets, you can push up the sleeves or wear it long, so it can be worn a little big.
• For some long, heavy coats, a little kid might get “swallowed” in an oversized jacket that is not very “scrunchable.”
