What to wear when meeting potential spouse family for the first time.

Hi guys M 26 from Karachi. I wanted to ask what should one wear when visiting girls house for rishta. My brother wore kurta shalwar however his body type is completely different from mine (tall and overweight). In my case I'm short (5'4) and kind of fit, the girl wants me to wear formal tucked shirt however personally I absolutely hate it. It makes me look even more shorter.

Do you guys have any suggestions? I'm thinking about wearing polo with good fit, dress pants and clean socks.

Also any other recommendations on what to do and what not to when vising them.... I'm extremely anxious tbh 😂 this is my first time going to meet for rishta and hopefully last.
