Nicolas Villalba’s sense of fun is evident in his designs. Need an imaginative costume for Mardi Gras or a masquerade ball? He can make it, including the mask. He can also do more casual and subdued, such as a beach wedding bridal party in blue silk slip dresses and their groomsmen counterparts in linen seersucker suits. He’ll fix fashion emergencies at his Design District studio and can even make linens for your home.
