Sergio Hudson Size Guide: US, UK, EU and IT Sizes Explained

Sergio Hudson uses US sizes 0 to 16 and the label states its fitted pieces run true to size, so take your usual US size. At Sergio Hudson at Coveti the same pieces are listed on the UK ladder, where a US 0 is a UK 4 and a US 8 is a UK 12. The chart below converts every size for pieces such as the Green Tulip Dress and the Raspberry Single Breasted Blazer, and works across our designer clothing.

How Sergio Hudson fits

Hudson cuts close to the body. Jackets are shaped at the waist, with strong shoulders that should sit at the edge of your own shoulder, never past it. If the Green Double Breasted Jacket pulls across the buttons when closed, take the next size. Skirts and trousers sit high, at the natural waist, so choose them by waist measurement rather than hip. The Black High Waisted Boot Cut Pant and the Black Pencil Skirt include 5% spandex, which gives a little ease; the pure wool raspberry boot cut gives none, so size up between sizes.

Fit by category

Measuring yourself

Measure your bust at the fullest point, your waist at the narrowest point, and your hips at the widest point, keeping the tape level. Compare the waist figure first for skirts and trousers, and the bust and shoulder for jackets. Hudson designs for curves, so if your waist and hip sit in different sizes, buy the jacket and the trouser separately in the sizes that fit each, since every Sergio Hudson suit is sold as separates.

Alterations

The boot cut trousers are cut long for a heel, so most people hem them. Jacket sleeves can be shortened from the cuff, but the six button cuffs on the collarless jackets need a specialist. Leave the shoulders alone; they carry the shape of the jacket. The Coveti concierge can check a piece against your measurements before you order.
