🧥 What Makes a Coat an Investment Piece?

Not all coats are created equal. Here’s what defines a coat worth investing in:

1. High-Quality Materials

Wool & Cashmere: Durable, warm, and naturally insulating. Look for blends with ≥70% wool or ≥10% cashmere.
Virgin Wool: Untreated, resilient, and exceptionally long-lasting.
Cotton Twill or Gabardine (for trench coats): Wind- and water-resistant, made to endure years of wear.
Double-Faced Wool: Reversible, soft, and eliminates the need for lining.

2. Timeless Cuts

Longline Wrap Coat
Double-Breasted Military Coat
Single-Breasted Overcoat
Classic Trench Coat
These shapes have transcended trend cycles for decades and continue to look current year after year.

3. Excellent Construction

Look for reinforced seams, precise topstitching, fully lined interiors, and metal or horn buttons over plastic.
Made in UK, Italy, or USA often signals higher quality craftsmanship.

4. Neutral Colour Palette

Stick to camel, navy, grey, black, or taupe for maximum versatility and longevity.

Styling Advice: Choosing the Right Investment Coat

1. For Work & Smart Outfits

Opt for a single-breasted or belted wool coat in navy, camel or black. Wear over suits, trousers or structured knitwear.

2. For Everyday Errands

Choose a double-faced wrap coat or oversized trench. It layers easily, moves well, and pairs with everything from denim to dresses.

3. For Harsh Weather

Consider a wool-down hybrid coat or lined wrap coat. Brands like Arket and Everlane offer structured warmth with function.

4. For Travel & Light Layering

A unlined wool coat in a neutral shade is ideal—lightweight but polished. Harris Wharf and COS excel here.
