How do I get my boyfriend to dress better? /u/running_savant99 /r/malefashionadvice

I’ve recently started dating a guy (M31) who is successful, kind, funny and everything a girl could ask for. BUT he only wears athleisure (running/gym) clothes or items he gets from competing in races or events with logos on them. I’m all for being comfortable, but I wish he would put some effort in to wear nicer non-exercise clothes when we go out. I recently saw him in a nice button up shirt and it elevated his look A TON. I was much more attracted to him, simply because of this. I’m a 28F and I put in a lot of effort with dressing nicely when we go out.
HOW do I get him to dress better and invest in some nicer, non-athletic clothing without seeming like I’m trying to change him or being judgmental?
