Techies ought to treat themselves—and their overworked gadgets—to a major facelift before the year ends. Spruce up smartphones with a pop of color or some glittering crystals. From the brand’s Wonders collection is Fendi’s Blossom appliquéd leather iPhone case, which comes with bright red pyramid studs, hanging silver legs, and a suede backing in sky blue or baby pink. A more daring pick would be an embellished, printed, and textured leather iPhone case from Dolce & Gabbana. All items from this selection feature statement patterns and crystals arranged to look like various flora.
