Fit notes
- Grip socks are knitted to fit close. Between two sizes, take the smaller one for a snug fit or the larger one if you have a high instep.
- Toeless socks use the same sizes. The toe band should sit just below the base of your toes.
- Sets come with every pair in the size you choose.
- Shrugs and wraps are sized by bust measurement. The Fan Shoulder Wrap is one size.
- Towels and bags are one size; their measurements are listed on each product page.
