Most of the time, exchanges between you (shopper) and them (salespeople) can be best defined as “limited.” You ask for an opinion, and they respond with some version of “itlooksgreat,” or “noyourhipsdon’tlookbig,” or “ofcourseyoushouldbuyit.” Unless, that is, you’re shopping at No. 6, a new boutique in Little Italy where friendly help is also honest help, and where they really do want to pull together a flattering outfit for you. This probably has something to do with the fact that owners Karin Bereson and Morgan Yakus are stylists by trade: They live to make people photo ready. And their shop looks just like a studio set. Airy and minimalist, it’s filled with racks of vintage clothing and accessories from the Victorian era to the early ’80s — as well as new items you’ll want to add to your faves checklist: made-to-order Sven clog boots, Jacqueline Schnabel shoes, Miroike clothing, and a rotating selection of jewelry designed exclusively for the shop. With a nonintimidating approach, they offer suggestions on which fits and styles work for you. And your hips. No. 6, 6 Centre Market Place, between Broome and Grand Streets (212-226-5759).
