I am a ironworker at a shipyard I don't own a suit and tie for various reasons. Anyways my sister is having a destination wedding and I don't like her fiancé parents they don't like tradespeople. Is it unreasonable to tell her I will attend only if you foot the bill after all it's your wedding you want me there you pay for it. I am 6,8 367 pounds so a custom suit for someone my size won't be cheap.
