Theory Irving Short Sleeve Button-Up Shirt — Eclipse

Keep cool and polished in this lightweight black button-up, tailored from a breathable cotton-polyester blend perfect for warm-weather styling. The spread collar and short sleeves deliver crisp, classic tailoring, while the pure black fabric is a Deep Winter essential—clear, commanding, and endlessly versatile. The smart drape and easy-care composition make this a reliable foundation piece for both business and casual layering. Style with crisp white shorts and silver accessories for fresh, high-contrast ease; layer under a sapphire blazer with true navy trousers and cobalt tie for boardroom depth; or wear open over a ruby-red tee with charcoal chinos for polished weekend style.
