Why You'll Love It

- Low-Maintenance Finish: A wrinkle-resistant fabric keeps you looking crisp with far less ironing required.
- All-Day Freshness: Odour-neutral material helps you stay fresh through extended wear in the office or beyond.
Perfect For
Office meetings and presentations, layering under a suit for formal occasions, smart-casual evenings out, or travel days where comfort and a sharp look both matter.
Care Instructions
- Machine wash cold with similar colours.
- Do not tumble dry; hang to air dry.
- Iron on a low setting if needed, though the wrinkle-resistant finish minimises this.
- Avoid bleach and harsh detergents to protect the stretch fabric.
