How do you act when you have to be around more... provocatively dressed women? Am I over thinking this?

I’ve always dressed conservatively (no cleavage and nothing too short or tight). Maybe it’s my own insecurities projecting here, but it feels like they instantly judge me and treat me with disgust. I’m talking about the “Instagram models,” I’m in the gym and beauty business so I encounter them a lot and would like to fit in a little more.

I am always friendly and polite but it doesn’t seem to matter. It’s like I can’t be part of their group unless I indulge in plastic surgery, Botox, and tons of makeup.

Any advice?
