Nice polo

Fantastic polo shirt. Size was true to fit. Color is amazing. It’s soft and it has held up through washes since Christmas.

A great gift for a young gymnast.
Size: 9 Years, Color: White
Bought this for a young friend. Heat applied a hot pink "gymnast" stencil to the back and a smaller one on the front. She loved it. Nice quality material with good construction. Would recommend as a good value for the money.

A bit expensive for what it is
Sweatshirt as expected in quality and color. Minus 1 star for price. A bit too expensive, better value found at a mall.
