My family-in-law always dresses really fancy?

[dureau]

And they always want me to too. I don't mind dressing up every now and then but I'm more of a sporty girl so it's really annoying. I just want to be me. But this morning my grandmother-in-law asked me to wear these nicer clothes and we're just going to the airport. I know why she wants me to wear them because they make me look slimmer and show off the weight I've been losing and she's been most likely gossiping and bragging to her sister (the person we're picking up at the airport) and wants to show me off. It really bugs me even though I said I would since she asked so nicely but still.. How can I keep them from trying to change me? How can I keep being me without disrupting the "harmony".

You tell them nice and up front.
