How to Wear a Peplum Jacket: Blazers, Proportions and Fit

A peplum blazer is a jacket fitted at the waist with a short flared panel below it. It does one thing very well: it makes a waist, whatever your shape. The trick is the proportion underneath, because the flare adds volume at the hip. This guide covers what to wear with one, how it should fit and the peplum jackets Coveti has now, from Dice Kayek, the Paris house that has made the shape a signature.

Key facts

• What it is: a tailored jacket with a fitted waist and a short flare over the hip.
• Why it works: it creates a waist, so it suits straight figures and balances wide shoulders.
• Best with: slim trousers, straight jeans, pencil skirts and column skirts.
• Avoid: full skirts and very wide trousers, which double the volume.
• At Coveti: 5 Dice Kayek peplum jackets, $2,880 to $3,600.

Peplum jacket and peplum blazer: the difference

The two names are used for the same idea. A peplum blazer is cut like tailoring, with lapels and a structured shoulder; a peplum jacket can be softer, collarless and cropped, like the denim and satin versions below. Both have the fitted waist and the short flare, and both are worn the same way: closed, over a thin layer, with a narrow bottom half.

What to wear underneath

A thin layer. A white poplin shirt with the collar out, a fine knit and a silk camisole all lie flat under the fitted waist. A chunky knit fights the shape. Button the blazer: a peplum is designed to be worn closed.

What to wear on the bottom

Keep it narrow. Straight-leg jeans, slim tailored trousers, a pencil skirt like High-Waisted Midi Pencil Skirt in Blue and a column maxi skirt all let the flare stand out. A wide trouser can work if it is high-waisted and soft, but it needs a heel.

For work, evening and the weekend

For work, a black peplum blazer with a white shirt and slim trousers. For evening, the same blazer over a satin column skirt, with a brooch on the lapel. At the weekend, Tailored Peplum Jacket in Denim with straight jeans and a flat shoe.

Fit checks

The waist seam should sit at your natural waist, not above. The shoulders should end at your shoulder bone. The flare should stop around the top of the hip. Raise your arms: if the waist rides up a long way, size up.

By body shape

On a straight figure, a peplum makes a waist. On a pear shape, choose a short flare that ends above the widest point of the hip. On an hourglass, the fitted waist is the point, so go close. On a petite frame, choose a short jacket and keep the bottom half one colour.
