Cross-gender

Women shopping menswear, men shopping womenswear

There is no single men’s-to-women’s offset. It is one size at adidas and about one and a half at most US brands, so check which brand you are buying rather than carrying one number across all of them. When a listing gives a measurement, convert by that instead: length in centimetres is the same number for both.

Gucci-Gucci uses separate men's and women's EU sizing. Use the brand chart.
Eyewear fit

Frames are measured, not sized

  • ·Eyewear fit is frame measurements (lens width, bridge, temple), not clothing sizes
  • ·Finlay & Co. wayfarer-style frame: about 13.5 cm wide and 4.5 cm high
  • ·Finlay & Co. Chiltern: steel nose bridge with adjustable pads

Sizing varies by collection within a brand, these are general guidelines. For a specific piece, check the collection page for the per-collab sizing note. Besot cannot guarantee fit; when in doubt, consult the platform listing's measurements.
