Since debuting in 1983, this milliner has topped off runway looks for Donna Karan, Ralph Lauren and Oscar de la Renta. The brand’s first New York boutique closed in April 2011, but the sophisticated assortment of hats is now available at its shop on the Upper East Side—a location chosen for the neighboring luxury shops frequented by Kokin’s typical clientele. In an attempt to veer away from the cutesy vintage aesthetic seen at other hat shops, the sleek all-white space is decorated with metallic floors, multiple mirrors and bright lighting meant to showcase the hats’ true textures and colors. For bold ladies, statement makers such as plumed Via Spiga felt wide-brimmed fedoras ($395) and house-label floppy hats outfitted with a skinny studded ribbon ($325) will add oomph to any ensemble. For customers seeking simpler embellishments with the same luxe quality, cloches featuring metal buckles ($345) or done up in chenille fabric ($365) are great picks.
