Reiss x McLaren Size Guide
Reiss is a contemporary British fashion brand renowned for sophisticated, design-driven clothing and accessories that combine classic style with modern cuts. The Reiss x McLaren collaboration brings premium tailoring and elevated essentials with a sporty edge, reflecting both brands' commitment to precision and performance. Reiss sizing is true to size, meaning you should order your usual UK size. The brand does not employ vanity sizing, offering authentic fit across an extensive range from XS through to 3XL. All items are listed in UK sizes, and every product includes detailed "Design and Fit" descriptions with model sizing information to guide your purchase.
How to Measure
For the most accurate fit, follow these measurement steps wearing minimal clothing with a soft tape measure kept snug but not tight against your body.
- Chest: Measure around the fullest part of your chest, keeping the tape close under the arms with arms relaxed at your sides.
- Waist: Measure around your natural waistline, typically at the smallest part of your torso. The tape should sit comfortably without pulling.
- Hips: Measure around the fullest part of your hips and bottom, approximately 20 cm below your natural waistline for accuracy.
- Inside Leg (Trousers & Jeans): Measure from the very top of your inside leg down to your ankle bone. Wear shoes with a similar heel height to those you'll wear with the trousers.
- Sleeve Length: Measure from the centre back of your neck, across your shoulder, and down to your wrist bone with your arm relaxed at your side.

Product-Specific Guidance
Coats & Jackets
Reiss coats and jackets are tailored with a contemporary fit and are designed to be worn with layers. The brand is noted for a slightly longer cut in the body, which suits taller frames. If you're between sizes, consider that a Medium (UK 10–12) typically accommodates a jumper underneath without excess fabric. Always check the "Design and Fit" notes on the product page, as the model's measurements are listed to help you gauge fit accurately.
Trousers & Jeans
Reiss trousers and jeans are cut true to size with a modern, tapered silhouette that flatters a range of body shapes. The brand offers both mid-rise slim and straight fits. Measure your inside leg carefully when ordering, and note that the inside leg measurement should be taken from the top of your inner thigh to your ankle bone. Reiss does not employ vanity sizing, so your usual UK size should fit well.
Dresses & Occasion Wear
Dresses at Reiss are designed with sophisticated tailoring and precise seams. The brand's contemporary aesthetic means dresses follow a modern, slightly fitted cut rather than a loose or oversized silhouette. Always refer to the product's "Design and Fit" description to see how a particular style runs. If you typically wear a UK 12 in tops but a UK 10 in trousers, try both sizes on dresses to determine which suits the particular cut.
Shoes
Reiss footwear is cut true to size. Measure the length of your foot from heel to toe tip and consult the foot length column in the size chart above. If you are between sizes, consider the style: closed-toe shoes typically offer less flexibility than loafers or sandals. The brand provides consistent sizing across collections.
Sizing Tips
- Reiss sizing is true to size with no vanity sizing applied. Order your usual UK size unless the product description states otherwise.
- Every product includes a "Design and Fit" description that specifies the model's size and how the garment fits. Read this carefully before purchasing, especially for coats, dresses, and occasion wear.
- Reiss is noted for tailoring garments to be slightly longer in the body, which suits taller frames well. If you are 5'3" or under, consider Reiss's petite collection, which is designed specifically for proportions below that height.
- If you are between two sizes, refer to the chest, waist, and hip measurements in the size chart above and compare them with a well-fitting garment you already own. This is more reliable than online fit descriptions.
- The brand offers both numerical sizing (4, 6, 8, 10, 12, 14, 16) and alphabetical labels (XS, S, M, L). Check the product listing carefully, as some styles use one system and others use the other.
- For shoes, always measure your foot length in centimetres and cross-reference with the foot length column in the footwear chart. Sizing varies significantly across shoe styles (formal shoes, trainers, slippers), so foot length is the most reliable guide.
- If you are purchasing from Vinted or another secondhand platform, request detailed measurements of the chest, waist, and hip rather than relying on the size label alone, as vintage Reiss items may fit slightly differently from current production.
