Sizing Tips

  • Measure your best-fitting shirt flat for the most accurate width and length.
  • If you're between sizes, choose the larger size for a looser fit.
  • Width is measured across the chest one inch below armpit when laid flat.
  • Length is measured from high point of shoulder to finished bottom hem.

Loved it!

My grandchild loved the t-shirt and got a kick out of being that many months, days, hours, minutes and seconds years old. She put it on immediately and wore it the rest of the evening. I plan on buying these t-shirts every year. (BTW, I bought it true to her age but she's very petite so it's a little large on her. BUT, that means she can wear it for the whole year she's eleven!)
