Although most parents will allow the prospective bride and groom to meet alone, you may end up with a first meeting with the guy and his entire clan.
What to wear?
A pretty kurta in a complexion enhancing colour teamed with tights or an elegant sari (check with your parents) are good options.
A simple pendant and earring will make you look elegant and pretty.
Fresh natural makeup / nude look will give you confidence, while making sure that prospective in-laws do not feel you are trying to hide behind paint. You can opt for light pink or French manicure.
How to greet?
Generically a standard Namaste with folded hands and a smile will save you from the questioning looks from elders that may come with a “Hi” or getting labelled as “too traditional” if you opt for touching the feet.
Things to do / not to do
Sitting: Your parents / prospective in-laws may ask you to sit near them / their son. Do so gracefully. No rolling the eyes, looking shocked or uncomfortable.
Talking: Once you’ve exchanged the pleasantries, follow their cues and let them start the talking. Avoid being overfriendly or too restrained. Tone yourself down. Be polite. Skip embarrassing incidents and sticky subjects. If you think you are not comfortable with the line of questions being asked, change the track of the conversation.
With the guy: Don’t try to interview the guy in front of his parents. They may think that you will intimidate him.
Don’t be a fake: Be your own self. Don’t portray a wrong image; this can lead to a future disaster. If you don’t know how to cook, say you’ve never had a chance or need to cook till now and who can predict what the future may bring.
Think of this whole situation as an interview with a prospective employer. You need to be the best version of yourself and make the interviewer want to hire you.
