Dress up for the occasion
You cannot expect to gel in with the rest of the guests if you are not properly dressed up for the occasion. Wear a tuxedo or a fancy looking suit if you want to get inside unnoticed. Don’t forget to do a little homework regarding the wedding couple and try to get the required information from the guests around.
Get inside without an invitation
While entering the reception, congratulate the wedding couple and use the words like May they live happy ever after. Or you can choose to delay a little and enter the wedding reception after it is already started. This way you can sneak in unnoticed as most of the guests will be busy drinking and dancing and they won’t pay much attention to your arrival.
Pretend to be a relative
You can always pretend to be a distant relative of either the groom or the bride. Usually they don’t ask you much questions but in case they do, you can always make stuff up.
Do not explain yourself
Do whatever you do but do not explain yourself. Try not to talk about yourself and if someone inquires about you, change the topic of discussion at that very instant to avoid any mishaps.
Listen to what people are talking around you. Try to get as much information as possible about the bride and groom so if someone asks you, you will be able to answer their questions and satisfy them to some extent.
Dance with the ladies
Do not hesitate in dancing with the ladies. However, do not go directly to the prettiest of the girls straight away and first try to gel in.
Finish with a bang
Leave the party with a bang. You can always pretend to be drunk and give a funny toast to wrap things up.
