All 207 Threads apparel is printed exclusively on Comfort Colors garment-dyed fabric. If you've never worn Comfort Colors before, here's what to expect: a relaxed, slightly oversized fit that feels broken-in from the first wear. These are not slim-fit garments. They're designed to be comfortable, casual, and easy to layer.

Most customers find their usual size works perfectly for the signature relaxed fit. If you prefer something more fitted, size down. If you want an oversized, streetwear-style look, size up.

All measurements below are in inches and represent the garment laid flat. Because Comfort Colors are garment-dyed and preshrunk, expect minimal additional shrinkage with proper care (wash cold, tumble dry low).

How to Measure

Chest Width: Lay the garment flat and measure straight across from armpit to armpit.

Body Length: Measure from the highest point of the shoulder seam down to the bottom hem.

Sleeve Length: Measured from center back of the neck to the end of the sleeve cuff.

Fit Tips

True to size for a relaxed fit. Comfort Colors are designed to be roomy and comfortable, not slim or fitted. If you normally wear a Large in most brands, a Large here will give you that classic, laid-back fit with extra room in the shoulders and chest.

Want it more fitted? Size down one. A Medium in Comfort Colors fits closer to a standard Large in most brands.

Want it oversized? Go with your usual size or size up one for a looser, streetwear-style fit. Our hoodies and crewnecks are especially popular sized up as cozy beach layers.

Shrinkage: All Comfort Colors garments are preshrunk during the garment-dye process. With proper care (cold wash, low heat dry), you'll see minimal additional shrinkage. Avoid high heat, which is the main cause of shrinkage in any cotton garment.
