Find My SizeNike True to Size Reviews from Reddit
"I almost always go up a half size. I've found Nikes are much more likely to run small/fit snug and I've never regretted sizing up"
"When buying T-shirts on the Nike website, make sure to read the "Size & Fit" section in the product description. It will tell you if its a "Standard Fit" which means go TTS or "Loose fit for a roomy feel" which means it runs big and you should size 1 down. SB T-Shirts usually run big"
