Size Guide

Our production team have hand-measured each garment, so the sizes you see below are reflective of this style. Compare the sizes below to one of your favourite fitting garments at home to find your perfect size. 

Measurements are taken from the outside of the garment, lying flat and then doubled for your convenience. Therefore a 20" chest lying flat will measure 40" around.

Unstructured Tailoring

Oliver Spencer has long been renowned for his unique brand of relaxed, unstructured tailoring. Taking out the stuffy structure of his jackets creates a much softer and more natural drape over the body, providing a casual aesthetic that is degrees more versatile. We think of our suits like an extension of our casualwear - comfortable, easy to style, and thoroughly modern.


Texture plays an enormous part in Oliver Spencer tailoring collections, helping to create wonderfully tactile garments. The Arnold cloth is one such fabric - cut from a soft 100% ecological linen cloth and featuring a subtle vertical stitch detail. It's a great way to wear black in the summer months thanks to the breathability of the linen.

Cut & Construction

The Wyndhams jacket is our one-button, unstructured jacket with a short peak lapel. It combines the modern suit silhouette with the comfort of a shirt thanks to the soft linen fabric, embodying the casual authority of a traditional suit jacket. Unlike typical English suits that rely on full- or half-canvassing for structure, Oliver Spencer’s suits embrace a more natural European style, unstructured and draped for total comfort and effortless style.

Tailoring & Alterations

At Oliver Spencer, we understand the importance of a great fitting suit or separates. We are all very unique in our body shapes and so no two people will ever fit our suiting exactly the same, which is why we ensure that our trained staff measure you up to guarantee a perfect fit. We use expert local tailors to make the necessary alterations required to provide you with the perfect fit. For more information, read more here.
