Outerknown Size Guide
Outerknown is a premium sustainable clothing brand that combines environmental responsibility with surf-inspired design. The brand follows standard UK sizing conventions, making it accessible for UK and European shoppers. Outerknown's fit is contemporary and versatile, designed for those who value both ethical production and refined style. Whether selecting classic tees, shirts, or outerwear, accurate measurement is essential to ensure the relaxed yet refined fit the brand is known for. The brand uses high-quality sustainable fabrics including organic cotton and recycled materials, which may experience slight initial shrinkage (typically 2–3%) with the first wash.
How to Measure
- Chest: Measure around the fullest part of your chest, keeping the tape measure horizontal and snug but not tight. Ensure the tape sits level across your shoulder blades and under your arms.
- Sleeve Length: Wear a fitted shirt and measure from the centre back neck, across the shoulder, and down the outside of your arm to your wrist bone. This measurement ensures sleeve length will be comfortable for layering and movement.
- Waist: Measure around your natural waistline at the point where your trousers or belt typically sit. Keep the tape comfortably loose without pulling.
- Inseam (Inside Leg): Measure from the top of your inside leg at the crotch down to the floor. Trousers and shorts should be measured at this point for accurate length.
- Timing: Take all measurements in the evening when your body is at its largest, as feet and torso can swell during the day. Compare your measurements directly to the Outerknown size chart below.

Product-Specific Guidance
Shirts & Tops
Outerknown shirts and tops are designed with a relaxed, modern fit that works well for both casual wear and layering. Pay particular attention to sleeve length, as Outerknown pieces are cut to sit at the wrist bone. If you have longer arms or prefer a cropped look, you may wish to size down. Always check the product description for any item-specific fit notes, as some pieces such as fitted tees or tailored shirts may run slightly narrower than standard sizing.
Outerwear & Jackets
Jackets and outerwear from Outerknown typically allow room for layering underneath. If you intend to wear heavy base layers or knitwear beneath, consider sizing up. The brand's surf-inspired designs often feature slightly dropped shoulders and a relaxed silhouette, so sizing to your true chest measurement will provide the intended aesthetic.
Trousers & Bottoms
Outerknown trousers follow standard UK sizing conventions. Measure your waist at the point where you naturally wear your trousers, and always check the inseam length (also called inside leg) before ordering. The brand's bottoms tend toward a straight or slightly tapered fit, so if you prefer a looser cut, you may wish to size up.
Shorts
Shorts from Outerknown are typically cut for a comfortable, relaxed fit suitable for water activities and warm weather. Refer to the waist measurement on the size chart rather than relying on your usual clothing size. Inseam length is crucial for shorts; measure from your natural waist to just above the knee for the classic Outerknown length.
Sizing Tips
- Sustainable fabrics used by Outerknown, particularly organic cotton and recycled materials, can shrink slightly (2–3%) with the first wash. Measure generously and always check individual product descriptions for care instructions.
- Outerknown's contemporary fit is designed to be relaxed without being oversized. If you're between sizes, compare the chest measurement to your preferred fit rather than relying on your usual size label.
- Sleeve length is critical for Outerknown pieces. The brand cuts sleeves to sit precisely at the wrist bone, so if you have particularly long or short arms, check this measurement carefully before ordering.
- For outerwear and layering pieces, always consider whether you'll be wearing thick base layers or knitwear underneath. If layering is your intention, sizing up half a size can provide comfort without compromising the brand's intended silhouette.
- Take all measurements in the evening when your body is at its largest, as this provides the most accurate sizing. Avoid measuring immediately after exercise or when bloated, as these can skew your results.
- Always check the specific product page before ordering, as some limited-edition or collaboration pieces may have unique fits or sizing notes that differ from standard Outerknown sizing conventions.
- If you're ordering from outside the UK and EU, be aware that Outerknown uses UK sizing, so conversions to US or EU may be necessary. Refer to the size chart above for accurate conversions.
