Gc Size Guide
At Gc, we believe that the foundation of great style is a perfect fit. Our global collection is designed for the modern, international lifestyle, bringing together premium fabrics and precision tailoring. Because we distribute our collections across various regions, we understand that sizing can often be a source of frustration. Whether you are shopping from London, New York, or Paris, our mission is to provide you with the clarity needed to shop with absolute confidence. Our sizing philosophy focuses on anatomical accuracy, ensuring that our garments move with you, providing both comfort and a sharp, sophisticated silhouette. We cater to a diverse, global clientele, which is why our guides bridge the gap between UK, US, and European standards, alongside detailed physical measurements in both inches and centimetres.
How to Measure
- Chest & Bust: Wrap the measuring tape around the fullest part of your chest or bust. Ensure the tape is level across your back and stays snug against the body without compressing the tissue. For the most accurate result, wear a well-fitting, non-padded bra.
- Waist: Locate your natural waistline, which is the narrowest part of your torso, typically situated just above the belly button. Wrap the tape around this point, keeping it level and comfortable.
- Hips: Stand with your feet together and wrap the tape around the widest part of your hips and buttocks. It is essential to ensure the tape remains horizontal to avoid underestimating your size.
- Foot Length: Place your foot flat on a piece of paper against a hard surface. Trace the outline of your foot, keeping the pen vertical. Measure the distance from the back of the heel to the tip of your longest toe in centimetres for the most precise fit.
- Inseam: For trousers, measure from the uppermost part of your inner thigh down to the ankle bone.

Product-Specific Guidance
Premium Tops & Knitwear: Our tops are designed with a standard fit. If you prefer a more relaxed, oversized aesthetic, we recommend selecting one size larger than your measured chest size. For a tailored, slim-fit look, stick to your standard size.
Tailored Trousers: Our trousers rely heavily on waist and inseam accuracy. If you find yourself between waist sizes, we suggest sizing up and utilizing our tailoring services or a local professional to ensure the waist sits comfortably without pulling at the hips.
Athletic Footwear: For trainers and performance footwear, we recommend measuring your feet in the evening. As feet naturally swell throughout the day, this ensures your shoes will remain comfortable during extended periods of wear.
Sizing Tips
- Measure in the Evening: Always perform your body and foot measurements in the evening when your feet are at their largest to avoid purchasing sizes that are too restrictive.
- The "Two-Finger" Rule: When measuring for waistbands, ensure you can comfortably fit two fingers between the tape and your skin to account for natural movement and breathing.
- Size Up for Comfort: If your measurements fall exactly between two sizes, we always recommend selecting the larger size. It is much easier to tailor a garment that is slightly too large than one that is too small.
- Consider the Fabric: Be mindful of fabric composition. Items with high elastane content will offer more stretch, whereas 100% cotton or denim will have minimal give.
- Check the Brand Standard: While Gc follows international standards, always cross-reference our charts with your existing wardrobe to identify how our specific cuts compare to your current favourite brands.
- Account for Socks: When determining footwear size, always factor in the thickness of the socks you intend to wear with the shoes, especially for athletic or winter styles.
- Stay Level: When measuring your bust or hips, ensure the measuring tape is perfectly horizontal around your body. A tilted tape will result in an inaccurate, smaller measurement.
