Corset Belts: How to Wear One, Find Your Size and the Designer Versions

A corset belt is a wide, shaped belt that sits at the natural waist and pulls the silhouette in. Worn over a dress, a shirt and a coat, it changes the proportions of an outfit more than almost any other accessory. US Google searches for “corset belt” run at about 9,900 a month. Alaia has made shaped belts since Azzedine Alaia cut his corset belts in the 1980s, and the house still makes them in leather and perforated Vienne nubuck. Coveti carries 8 Alaia belts from $1,450 to $2,470. This guide explains how to wear one and how to choose the size.

Corset belt and bustier belt

A corset belt is shaped to curve in at the waist, often with a back closure. A bustier belt is taller and sits higher, nearer the ribs. The Alaia Tube Corset Belt is cut in nappa calfskin with thick tubular piping and a back buckle, and is 13 cm high. The Alaia Bustier Belt is perforated with the Vienne pattern and has scalloped edges, and is 12 cm high.

How to wear a corset belt

Over a long knit dress, a corset belt turns a column into an hourglass. Over a white shirt and full skirt, it gives a ballet line. Over a tailored coat, it shapes the waist and holds the coat closed. Keep everything else simple, because the belt is the focus. Black and brown belts go with everything; a colour is the more playful choice.

How to find your size

Measure your waist at the narrowest point, where the belt will sit, with the clothes you plan to wear under it. Alaia sizes its belts in centimetres, from 60 to 95 on most styles, so choose the size closest to that measurement. If you will wear it over a coat, measure over the coat.

Five ways to wear a corset belt

One: over a long black knit dress, with ballet flats. Two: over a crisp white shirt tucked into a full midi skirt, the Alaia ballet line. Three: over a long wool coat, belted at the waist, with boots. Four: over an oversized blazer worn as a dress, with bare legs and slingbacks. Five: over a slip dress at night, with a heeled sandal. In each case the belt is the one strong piece, and the rest stays plain.

Why the corset belt is an Alaia signature

Azzedine Alaia built his name on clothes that shaped the body, and his wide leather belts did the same job as his seams: they drew the eye to the waist. The house still makes them in smooth nappa calfskin and in Vienne perforated nubuck, the lace-like pattern the brand describes as inspired by mashrabiya openwork. A corset belt is also one of the more accessible ways to wear the Alaia silhouette without buying a dress.

Caring for a leather belt

Store a corset belt flat, not rolled, so it keeps its shape. Wipe smooth leather with a soft dry cloth, brush nubuck gently and keep both away from water.
