What is the shirt made of?

It is 100% combed ringspun cotton. That cotton is combed to remove short fibers, which gives a smoother, softer surface than standard cotton tees.

Which style should I pick?

Classic is the standard everyday cut. Heavyweight is a thicker, sturdier fabric, Streetwear is a looser cut, Premium is a finer fabric, and V-Neck, Vintage and Active are alternate necklines and finishes. Pick by the fit and feel you want.

Is it a men's or women's fit?

It comes in a Male Fit and a Female Fit. Choose the one that matches how you want the shirt to sit across the shoulders and body.

Is this an official Larry Bird or Celtics shirt?

No. It is an independent design sold through a print-on-demand marketplace, not licensed NBA or Celtics merchandise.

How should I wash it to keep the print?

Turn it inside out and wash cold, then tumble low or hang dry. Heat is what breaks down printed graphics, so avoid a hot dryer and a direct iron on the design.
