Unformal Wear, a local tee-shirt company that specializes in those tacky yet endearing tuxedo shirts, is hosting charity event, Rockin’ Cotton for a Cause, at the Field House to benefit cancer charity Alex’s Lemonade Stand. The entry fee buys you two hours of open bar, and a third of your cash goes directly to the cause. Attendees also get a sweet tux tee and a $5 deal on appetizers, plus a chance to win one of the many giveaways of the evening. Local musician Matt Spitko will be providing the tunes. Thursday July 22, 5 - 8p.m. ($30)

You don’t to be a kid to enjoy the zoo, especially not when there’s alcohol involved. At the Philadelphia Zoo’s Summer Ale Festival, you can sample a selection of craft beers in addition to local cuisine, while ogling exotic animals from alligators to orangutangs. Don’t miss Creatures of Habitat: A Gazillion Piece Animal Adventure, an exhibit of larger-than-life LEGO recreations of the zoo’s most popular animals. Of course, with your belly full of beer, you’ll be as thrilled as the eight -year-olds. Saturday July 24, 6:30 - 9:30 p.m. ($25-80)

So maybe you aren’t a fan of Rancid or NOFX but you’re still likely to enjoy the Punk Rock Flea Market, a semi-annual event organized by concert promoters R5 Productions. The proceeds go to keeping all-ages shows in Philadelphia a reality, so you can feel good about springing to meager $3 to enter upon a cornucopia of hipsters selling their old stuff and craftsters selling there handmade goods. R5 has managed to cram hundreds of sellers into the new location on Ninth and Spring Garden, so come early and stay late. Sunday July 25, 10 a.m. - 5 p.m. ($3)
