You’re always up for a little friendly competition. For the grade. For the biggest wedding. For the smartest, cutest baby. Want to try for best-dressed man? Tip him off to the clothes of Robert Geller, formerly one half of the daring Cloak menswear design team. Mixing classic cuts with more experimental cloaky details (an unexpectedly long silhouette on a conventional college sweater, button-flap details along a shirt’s band collar), the collection has solid structure and a luxurious hand. Standout pieces include a fishtail parka with unbelievably soft-as-bunny-fur lining (don’t worry, it’s all faux) and a khaki puff vest with sporty, sleek warmth. But you can keep your eye on the cotton pullover, gray and terry looped; it’s something you could sneak from his closet or just buy for yourself. Now there’s a good sport. Available at Stel’s, 334 Newbury Street (617-262-3348 or stelsinc.com). To see styles, go to robertgeller-ny.com.
