Hidden costs

Hidden costs are costs associated to weddings that either the couple or guests had not planned on.

Common hidden costs

For the couple

Honeymoon
Wedding rings
Day-after brunch
Undergarments
Hair and makeup trial, waxing, etc.
Rental of linens, tables, chairs, flatware, china, etc.
Tipping (not hidden, but sometimes forgotten till the last minute)
Delivery fee for the cake & cake cutting fee
In Kentucky, there is an "alcohol tax". If you have an open bar, you have to pay the state $11 per guest to serve them.
Stamps for non-standard envelope sizes or heavy invitations.
Cake cutting fee (some venues charge this if you bring in an outside cake)
Rental Mark-ups (several caterers we interviewed will coordinate your tent, table, china, rentals etc. but don't mention they mark these up 15%!!!)

For bridesmaids

Bridesmaids are often asked to pitch in for parties they might not even be able to attend.
Decorating the bridal suite: champagne, flowers, candles, etc.

For guests
