SISLEY Size Guide

SISLEY is a premium Italian fashion brand renowned for its contemporary, fashion-forward designs that balance elevated basics with effortless sophistication. Founded in Paris and now headquartered in Italy, SISLEY is part of the Benetton Group and specialises in clean Italian tailoring, city-smart silhouettes, and high-quality fabrics. The brand is particularly celebrated for its fitted blazers, stretch denim, structured dresses, and refined knitwear that appeal to style-conscious individuals seeking modern European elegance. SISLEY's sizing follows Italian standards and tends towards slim, close-to-the-body cuts, particularly in tailored pieces, trousers, and shirts. This guide will help you navigate SISLEY's sizing across apparel, jeans, footwear, and accessories to ensure a perfect fit every time.

How to Measure

To find your correct SISLEY size, follow these simple measurement steps. Use a soft measuring tape and wear minimal clothing for accuracy.

  1. Bust/Chest: Measure around the fullest part of your bust or chest, ensuring the tape sits well under your arms and spans your shoulder blades. Keep the tape relaxed and level all the way around.
  2. Waist: Measure around your natural waistline at the point where you find it most comfortable to wear a belt or waistband. This is typically where your body creases when you bend slightly forwards. Do not pull the tape tightly.
  3. Hips: Measure around the fullest part of your hips and bottom whilst standing with your feet together. Ensure the tape is level and relaxed.
  4. Arm Length: With your arm bent slightly, measure from the shoulder point down to your wrist bone. This is particularly important for fitted jackets and long-sleeved tops.
  5. Inside Leg/Inseam: Measure from the top of your inside leg at the crotch down to the floor or to approximately 2–3 cm above your shoe. This is essential for trousers and jeans. For accuracy, wear the shoes you plan to wear with the garment.
  6. Height: Stand barefoot with your back against a wall and measure from the top of your head to the floor. SISLEY provides height ranges to help match proportional fits.

Note: ±0.5 cm discrepancy on size measurements is possible. SISLEY items carry Italian sizes on the label; if you selected a local size conversion online, the label number may differ from what was displayed during checkout.

Fit Note for Women: SISLEY women's styles lean towards slim, close-to-the-body cuts, particularly in blazers, tailored jackets, trousers, and fitted shirts. If you prefer a more relaxed fit or have a fuller bust, broad shoulders, or a curvier silhouette, consider sizing up. Jersey dresses and knitwear offer more forgiveness than structured tailored pieces. Always review the product description for specific fit details (e.g., 'slim fit', 'regular fit', 'relaxed').

Blazers and tailored jackets are designed with a clean, slim silhouette through the shoulders and waist. Trousers feature a refined cut with a slight taper. If you prefer a looser, more relaxed fit, consider sizing up, particularly in outerwear.

Footwear Note: SISLEY shoe sizing follows standard European conversion. Measure your foot length in centimetres for the most accurate size selection. Feet can swell during the day, so measure in the evening for a more precise fit. If one foot is slightly larger, purchase shoes that fit your larger foot. Always check product-specific reviews for fit feedback, as some styles may run narrow or wide.

Product-Specific Guidance

Blazers & Tailored Jackets

Fit: Slim and tailored through the shoulder and waist, often fully lined for structure.

Sizing Tip: True to size is standard, but if you have broad shoulders, enjoy layering, or prefer a more relaxed silhouette, consider sizing up. SISLEY's tailored jackets are designed for a fitted, sophisticated aesthetic.

Trousers & Tailored Pants

Fit: High-rise, slim leg or tapered in stretch or cotton-blend fabrics with refined proportions.

Sizing Tip: Stick to your Italian size; the rise and leg taper are designed for a true-to-size fit. If you have a curvier silhouette or fuller hips, sizing up one size may provide more comfort.
