Lemon & Line bracelets are designed to be worn snug on the wrist and proper sizing is critical to clasp function. 
They should not float freely up & down the arm. We recommend using a tape measure to determine your correct size.
Measure just above your hand, on the snug side. Add .5", and that is your proper size.

 

In the above example, the proper size is XS. (6" + .5")

XS: 6.5"
S: 7"
M: 7.5"
L: 8"
XL: 8.5"
