Fashion and real estate have a lot in common: high and low risks, shifting markets, bursting bubbles, and new commodities. And both industries love their hot tips. Here’s one: Alice Ritter, one of our favorite up-and-coming designers. Her collection is already way popular with fashion insiders. That’s not so surprising considering Ritter hasn’t yet appreciated to couture value. Amenities — er, styles — include cropped ruffles (bolero coats), balloon sleeves (tops), collegiate pins (blazers), and tartans with snaps (school skirts). So on point with fall and winter trends, this stuff is as hot as a 3BR w/ W/D & pvt rftp. The modern, sculptural shapes and fit are also extraordinary. Unfortunately, such superb quality tends to go hand in hand with limited availability. So be prepared for bidding wars. Available at Albertine, 13 Christopher Street, between Greenwich Avenue and Waverly Place (212-924-8515); Kirna Zabete, 96 Greene Street, between Prince and Spring Streets (212-941-9656).
