I’m a Sikh, it’s impossible to over do it, make sure your hair style is head covering friendly.
Sikhs like a good drink, so eat what is on offer to line your stomach.
Us Sikhs can be a bit touchy and full on, so don’r be surprised if you are physically grabbed and dragged on to the dance floor. It also means people will reposition your head covering, touch your dress etc if they’re sat near you in the ceremony. Physical affection is more common in south asia, so that can be a challenge for some.
You may find food before the ceremony, so its usual to eat before hand as a group, often tables but no chairs so it isn’t hard to get people to shift for the ceremony.
Sikh life is child friendly, so don’t be surprised if children are running around during the ceremony.
Men and women sit apart, so if you’re taking a male partner you won’t be sat together during the ceremony.
It’s traditional to give a small amount of money, lots of Sikhs now act out the bride price ‘ceremony‘ so if you see some playful bartering between the dads with the bride in the middle that is likely whats happening. Some people now make the brides dad match the money the guests have given, so in some families it becomes a bit of a joke when a dad tight has a daughter who marries as everyone makes sure they give a bit more money to make him sweat.
Its actually quite common for the bride and groom to now know whats next, so will often have someone whispering in their ear before different parts of the ceremony.
