Avoid the dreaded "sexy or goofy?" conundrum this October 31st and choose to dress stylishly instead: FabSugar.com points out that Shopbop.com has a cute Masquerade party section. Unlike most costumes which end up discarded the next day, these pieces—from the likes of DSquared2, Alexander Wang and Juicy Couture—will stick in your closet far longer. Choose from spider web-y knits, tough black boots, and loads of lace and leather. Boo-tiful, no?
