T-SHIRTS
All the t-shirts on the website are unisex, so they are suitable for both girls and boys; you just have to guess your size.
To determine your t-shirt size, you only need a t-shirt that you have at home and like its size. Measure from the edge of the collar down to get measurement A, and from the bottom seam of the right sleeve to the left to get measurement B as indicated in the drawing.
