OKAY! So my roomie is a very good friend of mine. We've been buddies since high school but over the last 4 years we are almost besties. I recently moved in with her because her place is way too large for just her, and the rent is cheap so it's a win win for both of us. There's only one issue which requires a little backstory...

She used to think she was unattractive (never the case) and so over the last couple years she's gotten into a huge fitness regimen. Great for her right? Now this came with a newfound confidence. Walking around in sports bras, "pyjamas" that are basically undies made of sweatpants fabric lol now once again, I'm all for this newfound happiness in her own skin. What has me concerned, is if my gf (23f) has a problem with it. She's been over plenty since I moved in but she hasn't run into everything I have.

I'm not going to tell the girl whose helping me out to change what she does in her own home, but should I tell my gf? Like maybe a calm discussion now is worth more than an argument later? There is nothing and never will be anything romantic between my roomie and I, we don't see eachother that way and I love my gf more than anything. Just dunno if I'm stressing over a non issue lol

TLDR: My roomie is hot, often dresses half naked at home, even though we're not gonna bang should I warn my gf so she doesn't freak out when she sees my roomie doing dishes in her underwear

Thoughts?
