1 – NO RSVP The bride and groom are spending tons of cash (and probably some of their parents’ cash too) to make sure you have a great time and are well-fed. They need to account for the number of guests for the caterers and the venue space. Just send the pre-paid posted card. Trust us, the happy couple will be so glad you did! 2 – WEARING WHITE

This one is pretty classic and kind of unforgivable. If the bride is wearing white, and even if she isn’t, just avoid anything in the white or ivory color altogether. To be even safer, get the color the bride is wearing as well as her bridesmaids so you can avoid being mistaken for a member of the bridal party all night.

3 – SHOWING UP LATE

This one goes back to the RSVP rule. The bride and groom paid for you to eat and drink. Be there on time out of respect for the couple but also so you can take advantage of the delicious eats and fun cocktails. You won’t be sorry!

4 – BEING CRITICAL

You may not love the bride’s dress or her choice of decor and flowers. Save the gossip and banter for after the wedding so you can come across as supportive and loving. After all, the bride and groom have invited you to be present for the most important day of their lives. Show some love!

5 – DRINKING TOO MUCH

The open bar may be tempting but this is one to definitely avoid. Have fun, but definitely know your limits. You don’t want to be involved in a story that goes down in infamy!
