You have to be sure of yourself to buck the trend that has all the hipsters, tycoons, pro athletes and actors snapping up property in hot Downtown locations like the Flatiron, Chelsea or Tribeca. For example No. 1, we give you designer Zac Posen’s nifty purchase of a duplex penthouse co-op on the Upper East Side for $3.5M.

Let’s make a bet that Posen will use his talents to execute a remodel of the 2-bedroom, 2.5-bathroom co-op’s interior, which is slathered in wondrous colors and fabrics the likes of which haven’t been in vogue since Marie Antoinette. Still! There is something kind of sublimely French Rococo-ish about how the place actually does work, even with the drapes, sconces, wallpaper and old-school furnishings.

In fact, even if he keeps it as-is in its of museum-piece presentation, Posen has snapped up a pretty stellar abode according to LLNYC. First, it is located on the top two floors of an Emery Roth classic on a tree-lined street in one of NYC’s most elegant neighborhoods.

Second, it comes with a winding staircase and a massive, 1,800-square-foot terrace that no doubt spoke to the “Project Runway” judge. I mean, can you picture a team party with Tim Gunn, Heidi Klum and Nina Garcia holding forth on all that outdoor space?

Whatever he does with the place, it will be fabulous, thanks to the 11-foot ceilings, corner oversized floor-to-ceiling glass doors and a wood-burning fireplace with a Chesney marble mantel.

There’s also a formal dining room, kitchen with dining alcove and a maid’s room that doubles as an office.

Additional features include central air conditioning, a Sonos stereo system with in-wall speakers and — the real draw for the clothing designer: Seven large custom outfitted closets, four of which are walk-in.

The full-service co-op amenities include a doorman, gym, outside courtyard with a grill, a large laundry room, bike room and storage room. It is also pet-friendly.
