We recommend ordering 1 box set (20 pairs) for every 60 total wedding guests (women & men). To calculate our recommended number of box sets simply take your total guests count and divide by 60. For example: 120 wedding guests divided by 60 = 2 box sets (40 pairs). If the calculation is not a whole number, we recommend rounding up. Eg. 137 guests/ 60 = 2.28 = 3 box sets.
