[header] How to play flag football [title] Suit up. [step] Wear form-fitting athletic gear, such as t-shirts, shorts, sweatshirts, and sweatpants. Avoid baggy clothing, as well as anything with pockets or belt-loops, to reduce the chances of an opponent grabbing your clothes by mistake when they attempt to snatch your flag. 
Also avoid wearing clothes that are the same color as the flags that you will wear. Tuck your shirt into your waistband to keep the flags accessible.
