 What Is Smart Casual?

Smart casual is a blend of comfort and class. Think jeans with a blazer, or a midi dress with clean trainers. It’s about looking put-together without being overdressed.

Smart casual = Tailored comfort.

You’ll need versatile separates that layer well and mix between office, brunch, or evening wear. Key elements include:

• Structured blazers

• Polished jeans or chinos

• Fine knitwear

• Loafers, sleek trainers, or boots

• Button-down shirts or elegant blouses

• Simple, well-cut dresses or skirts
