Fit first. Fabric second. Everything else follows.
Online shopping is easier when you know what a fabric is likely to do and how a silhouette is intended to sit.
Linen
Breathable, natural and meant to relax with wear. Linen wrinkles; we consider that part of its character rather than a flaw.
Ribbed knits
Usually more forgiving than a flat knit because the rib structure creates stretch. For a cleaner fit, choose your usual size; for a softer line, consider the garment's intended silhouette.
Satin and fluid wovens
These fabrics create movement rather than structure. They pair especially well with matte textures such as cotton, denim and knitwear.
Tailored pieces
Blazers and trousers depend most on shoulder, waist and rise. Check each product's measurements when available rather than relying on the size label alone.
When in doubt
Use the measurements and fabric composition listed on the individual item. Fit can vary by maker, so those details are more useful than assuming every label fits identically.
