Summer Business Casual for Men — at Josephs

Eton shirts & loafers

The key to successful summer business casual dressing for men lies in sticking to a traditional color palette while adding interesting detail with the kinds of fabric you choose and infusing your look with elevated features. Elegant business casual looks suitable for warmer days can be achieved by selecting the right fabrics.

At Josephs, summer business casual is about looking sharp, staying comfortable, and keeping it effortless. No stiffness. No shortcuts. Just clean lines, quality fabrics, and timeless style that works from the office to dinner.

Summer business casual is about staying sharp without looking overdressed—or feeling uncomfortable by 10am. Get the balance right and you’ll look polished, relaxed, and ready for anything from the office to a long lunch.

1. Start with the right shirt

A great summer outfit begins with a quality shirt, and Eton shirts are built for exactly this purpose.

What to look for:

• Lightweight cotton that breathes well in warm weather

• Crisp but relaxed colours – white, light blue, soft pink, or subtle patterns

• Impeccable fit – structured enough for business, comfortable enough for all day

Eton shirts hold their shape, resist creasing, and look just as good at 8am as they do late afternoon. Wear them tucked with tailored trousers, or untucked with chinos for a more relaxed office environment.

2. Trousers that keep things light

Pair your Eton shirt with:

• Cotton chinos in navy, stone, or olive

• Lightweight wool trousers for a sharper look

• A clean belt in brown or tan leather

The goal is structure without stiffness. Slim or tailored fits work best, especially when worn with loafers.

3. Loafers: the summer essential

Nothing says summer business casual quite like a well-made loafer.

Why loafers work:

• Easy, refined, and seasonally appropriate

• Dressy enough for business, relaxed enough for warm days

• Perfect with chinos or tailored trousers

Styles that work best:

• Penny loafers for classic appeal

• Tassel loafers for a slightly smarter finish

• Suede loafers for texture and comfort

Stick to brown, dark tan, or navy. Leather soles keep things sharp; rubber soles add practicality if you’re on your feet all day.

4. Keep the details understated

Finish the look with:kiiA quality leather belt to match your loafers

• No-show or fine cotton socks

• A simple watch—nothing too bulky

The best summer business casual outfits look effortless because every detail has been considered.
