Fat Guy Needs Linen

Hi yall, I’m pretty fat and have very large tits :( (6ft, 245lbs). I am going to a wedding in India and the “style” everyone is going for is like those linen Pinterest type aesthetics. It’s in a weekish and I need to have 3 linen pant/shirt combos, 2 casuals and 1 professional. The budget is kinda low but I don’t wanna look bad in photos…. Anything in Canada I could look into for an option?
