We've just launched our first contest on Instagram! Post a throwback sports picture of yourself, wearing Dragonwing girlgear or not (but we hope so), and tag @dragonwinggirl. We're posting each entry from our account, so our followers -- who've doubled in the past few days! -- can vote. The photo with the most likes by Monday, August 11, will win a prize. Maybe one of our sports bras or compression shorts made just for tween and teen girls. Stay tuned. Check out all the great photos that have been entered. It's that simple. Now, it's your turn!
