As a typical Indian set-up of arranged marriage meeting, if the family is not that modern then you can think about wearing a nice kurti with plazo or leggings whichever you feel suits you most. Besides, you can also try some long suits or anarkali suits as well if you have any.
Ask about the next meeting if you want to move forward. Arranged marriages tend to happen pretty quickly, so there's no time to beat around the bush. You can say something like, “I've really enjoyed spending time with you. I'd like to set up a second meeting. What do you think?”
BEING IN BED WITH A STRANGER In most arranged marriages, couples generally spend more time making elaborate plans for the wedding rather than getting to know each other better. So, when they actually spend the first night together, they realise they are with a 'familiar' stranger, who's now their life partner.
Ask about their hobbies and interests. You might think it is a very basic question to ask, a lot can be deduced from the reply you receive. If you might be met with a person with completely different interests or hobbies might be difficult to live with.
