Rails Size Guide
Rails is a contemporary fashion brand specialising in elevated everyday wear, including shirts, blouses, dresses, and knitwear. Known for relaxed yet refined silhouettes, Rails designs are cut with a modern fit that balances comfort with sophistication. The brand's sizing is designed to be approachable across UK, US, and European markets, with consistent proportions across their womenswear and menswear collections. Whether you're selecting a classic button-up or a comfortable knit, accurate sizing ensures you achieve Rails' signature effortless aesthetic.
How to Measure
- Chest: Measure around the fullest part of your chest, keeping the tape measure parallel to the ground. Wear a standard bra (not padded) for consistency.
- Waist: Measure around your natural waistline, where your body naturally bends when you lean to the side. Keep the tape comfortably loose—not tight.
- Hips: Measure around the fullest part of your hips and bottom, approximately 7–8 inches below your natural waist.
- Length: For dresses and tops, measure from the top of your shoulder down to your desired hem length (e.g., knee, mid-thigh).
- Sleeve Length: Extend your arm to the side and measure from the centre back neck, across the shoulder, and down to your wrist.
- Measure in the evening: Feet and body dimensions can swell during the day. Take measurements later for the most accurate sizing.
- Use a soft measuring tape: Ensure your tape measure is flexible and not stretched. Measurements should be snug but not constricting.

Product-Specific Guidance
Shirts & Blouses
Rails shirts are designed with a relaxed, contemporary fit. If you're between sizes, we recommend sizing up for a comfortable, layerable silhouette. Pay close attention to sleeve length and shoulder width, as these vary by style. Check individual product descriptions for fit notes (e.g., "oversized", "tailored", "boyfriend cut").
Dresses
Rails dresses typically run true to size. For a more fitted silhouette, select your usual size; for a looser, effortless drape, consider sizing up. Always measure your inseam or desired hem length, as dress proportions vary significantly between XS and XL.
Knitwear & Sweaters
Knitted pieces from Rails have a relaxed fit. If you prefer a more fitted look, size down; if you like an oversized aesthetic, size up. Check the specific product page for sleeve length, as Rails offers both standard and elongated proportions across their range.
Denim & Trousers
Rails denim typically runs true to size in the waist but has a modern, straight-leg or tapered fit through the thigh and calf. Inseam length varies; measure from your natural waistline to your ankle bone for accuracy. Rails often offers full-length and cropped options.
Jackets & Outerwear
Rails jackets are cut with a contemporary fit and layer well over other pieces. Measure your chest and shoulder width carefully. If between sizes, choose the larger size for comfortable layering and movement. Check sleeve length closely, as proportions can vary by style.
Sizing Tips
- Check product photos and descriptions: Rails' website provides fit guidance for each style. Look for keywords such as "oversized", "tailored", "relaxed", or "boyfriend fit" to understand the intended silhouette.
- Size up if between sizes: Rails' contemporary fit is designed to be worn comfortably. If you measure between two sizes, opt for the larger size, especially for shirts, knitwear, and dresses.
- Account for fabric and wash: Different fabrics (cotton, linen blends, jersey) and finishes (raw, distressed) may affect fit. Read care and fabric content details before ordering.
- Measure your current favourite piece: Lay a shirt or jumper you love on a flat surface and measure across the chest (armpit to armpit) and from shoulder seam to cuff. Compare these measurements to the product dimensions listed on Rails' size guide.
- Be aware of brand-specific fits: Rails' contemporary aesthetic may differ from other brands you wear. Allow for a 1–2 size variance if switching from traditional or heritage-inspired brands.
- Review sizing reviews on product pages: Customer feedback often highlights whether a piece runs large, small, or true to size. Pay attention to comments about fit, especially from customers with similar measurements to yours.
- Consider your body shape: Rails designs appeal to a range of proportions. Petite customers may find standard lengths generous; taller customers should check inseam and sleeve lengths closely before checkout.
- Use Rails' UK shipping and returns: Free UK returns and duties included make it straightforward to try multiple sizes at home. Order two sizes if unsure, and return within the specified timeframe.
