Black leggings and bikini (a.k.a. lame-ass Batgirl costume) aside, your superhero powers are virtually useless.

Still, a girl shouldn’t go through life without feeling a slight twinge of bravery.

Slip into Emilio Cavallini’s latest collection of dresses for a glimpse of what saving the world could really feel like. Cavallini (the Italian of outrageous hosiery fame) has created a stretchy line of jersey knits that fit like miraculous body armor — they accentuate everything you have yet hide the weak spots.

But beware: Outfits can be deadly. Tight-fitting sleeves and bubble skirts reveal killer curves. Bell sleeves and plunging necklines might ease the release of those fembot guns.

An act you might want to save for next time the Batphone rings.
