Our favorite indulgence: the $650 Cotton Piqué Spa Robe by Léron, a boutique that specializes in custom-made linens. This sleek, unisex robe is made of Swiss cotton piqué whose long fibers are exceptionally smooth and lightweight. The waffle-like texture of the cotton piqué exterior helps maintain the robe's shape, while its terry-cloth lining is plush and supersoft on the skin. Now, that's a real luxury.
