The blazer is one of the hardest-working pieces in the COS wardrobe. Few pieces move as seamlessly between occasions, adding polish to everyday dressing while adapting easily to elevated settings. Thoughtful proportions, considered fabrics and versatile colour palettes ensure the blazer remains timeless. 


There are endless different ways to style a blazer. The key principles are: 


•  Balancing proportion through fit and layering. 

•  Adding structure to relaxed pieces through tailoring.  

•  Mixing casual and refined elements. 

•  Considering fabric and silhouette. 

•  Building multiple looks around one key piece.

1. DEMIN FOR EVERYDAY EASE


When considering how to style a blazer, denim remains one of the most versatile starting points. The contrast between relaxed denim and structured tailoring creates a sense of balance. 

 

Style an oversized blazer with classic straight-leg jeans – denim has an effortless, off-duty feel, while the clean tailored lines lend refinement. Keep the rest of the look simple with a white T-shirt, ribbed tank top or a fine-knit base layer depending on the season. 

 

Neutral blazers in black, navy, charcoal or chocolate offer the greatest versatility, pairing effortlessly with light and dark denim washes. Keep accessories and footwear understated – loafers or leather sandals add timeless appeal.

2. MATCHING TAILORING


Modern tailoring embraces ease through relaxed shapes and softer construction. Pairing a blazer with matching tailored trousers creates a coordinating set that feels considered yet understated. A tonal palette brings visual continuity while allowing texture and silhouette to take centre stage. 

 

A crisp cotton shirt, lightweight knit or ribbed cotton tank echoes the clean lines of tailoring. Opt for a classic leather tote bag and leather loafers or ballet flats.

3. CONTRASTING SILHOUETTES 


Contrast the sharp tailoring of a blazer with softer, fluid pieces to add visual interest and movement. A blazer styled over a slip offers an elegant balance between structure and softness. Wide-leg trousers in fluid fabrics such as silk add textural contrast and depth. 

 

Accessories further refine the look – a sculptural bag, understated jewellery and leather footwear reinforce the minimal aesthetic.

4. SUMMER TAILORING 


Tailoring is often associated with the autumn-winter wardrobe, but a blazer has equal styling power in the spring-summer season. A blazer and shorts in coordinating linen provides a modern take on summer dressing, retaining the clean lines of classic tailoring while introducing a relaxed, seasonal feel.  

 

Layer a blazer over a simple tank or T-shirt for a clean, minimal foundation. Leather sandals are relaxed yet polished, while loafers or ballet flats are essential for summer city breaks.

5. TRANSITIONAL DRESSING 


The blazer is an invaluable layering piece that bridges the gap between seasons. Fine-gauge knitwear or funnel-neck tops style effortlessly beneath a blazer, providing lightweight warmth. When the weather cools, blazers can be layered comfortably beneath oversized outerwear.  

 

Tonal and textural contrast lend character to transitional looks. Wool, brushed textures and jacquard add nuance. Complete the outfit with leather boots or loafers and seasonal accessories such as leather gloves and wool scarves.
