Tips & Tricks
  • Measure your fingers at the end of the day when they’re at their largest.
  • Cold weather can shrink your fingers up to half a size, so make sure they’re warm.
  • Lastly, alcohol and salt can make your fingers swell, so refrain from measuring them after cocktails and appetizers.
