Otegas is sized for the United States, so the sizes you see are the ones you already know.
Shoes
Shoes are listed in US men's sizes, and the Size Guide shows the matching EU size for each one. Loafers and slippers stretch slightly with wear, so if you are between two sizes we suggest the smaller one.
Shirts
Shirts are sized by US collar size. The letter beside each size shows the matching S to XXL size, so a US 15½ is a medium and a US 16½ is a large.
Knitwear, polos, overshirts and socks
Knitwear, polos and overshirts are sized S to XXL. Socks are sized by US shoe size.
