Peridot wore a sleeveless green V-neck uniform. Her suit is mostly medium green, with a dark-green diamond outline around the cut-out of her neck area, meeting to form the Yellow Diamond insignia at her solar plexus, with a dark-green portion between her chest and leggings. Her leggings cover her feet and feature yellow toes and diamond-shaped knee pads. She is never seen without her visor, which covers the top half of her face and tints her eyes yellow-green. She has a slightly curvy figure.
