Bring a bag of clean, gently used clothing to Buffalo Gal Vintage between 10 a.m. and noon, and leave with a different bag of clothes during the shop's Clothing Swap. Nothing to trade in? Bring a fiver and take home a bag anyway. Recycling seminars, a talk on the age and care of vintage wear, and a "Trashy Fashion Show" are also scheduled. Cash donations and leftover clothing go to Community Action Stops Abuse (CASA). 10 a.m.-4 p.m., Gas Plant Antique Arcade, 1246 Central Ave., St. Petersburg, free, 813-748-8334.
