All our T-shirts are 100% cotton.

While choosing a size for you, please, keep in mind the following things:

1. The regular size small is an adult size.
   Usually girls who like more fit t-shirts like the kids/woman sizes.
   For the t shirts we recommend a size 14-16 for a regular look and a size 12 for a tight look.
   We also have women's/men's fit t-shirts, which sizes are rather small (we usually recommend taking one size larger).

2. For kids' sizes, our general recommendation is:
   Size 18 for ages 12-14
   Size 16 for ages 10-13
   Size 14 for ages 9-11
   Size 12 for ages 8-9
   Size 10 for ages 5-8
   Size  8  for ages 4-7
   Size  6  for ages 3-5
   Size  4  for ages 2-4
   Size  2  for ages 1-2

3. All the shirts shrink a bit after the first laundry, and after using the drier.
 

Thank you,
