I saw Cry-Baby on Broadway last night and it left me longing for a nipped waist. Actually, I've been longing for a nipped waist since Mad Men debuted last year and since Michael Kors showed perfect Hitchcock heroines and since Caroline wore mint green on Bottega's fall runway. But I don't have a costume designer at my beck and call, my waist is much too big for most vintage skirts and it's too hot to invest in something from the runway that will just get squished against sweaty strangers on the subway. So, Isaac Mizrahi's envelope dress for Target will do just fine. It comes in pink, (which, yes, looks sort of like that Oscar de la Renta dress from Sex and the City) black or buttery yellow. Add or subtract belts, shoes, jewels depending on the destination and you can wear this dress pretty much anywhere. Now if I could just get Cry-Baby or Don Draper to take the subway with me, it'd be a swell summer.
