Telling my bf I dislike his fanny pack he uses to carry around his supplies

Throwaway account because my bf sometimes uses reddit.

My boyfriend (m) and I (f) have been together for almost a year (we’re both in our mid 20s). He was diagnosed with t1 a few years ago, before we met.

It took me a bit of time at the beginning to learn about his diabetes and how it affects his everyday life, but now it’s just another part of him to me. I am absolutely happy to lie down with him when he’s low and to count carbs in meals I cook for us. His diabetes is just another part of his life, so it’s part of my life. I love him, and his diabetes has never and could never have any effect on that.

He carries all of his supplies around in a very big and full fanny pack that he wears 100% of the time he’s not home. When he dresses casually, his fanny pack looks fine. But when he dresses nicer (such as polo, button up, or suit), it just looks ridiculous to me. I’m gonna be completely honest about my feelings about it so that I can get the best advice possible—when he’s dressed nicer, I hate the fanny pack. It just ruins his look and doesn’t fit at all.

I know that I could never understand what it is like to be diabetic and need to bring supplies everywhere. Please tell me if I’m being overly shallow and terrible about this. I’ve been doing research on how other diabetics carry around their supplies and found a sleek sling bag on Myabetic that I think could look great on him. I read that some people just carry around their pens and needles in their pocket, but I know my bf wouldn’t like that—he likes having it all organized in the same place all the time, which is why I’ve been researching nicer looking bag options that could work for him. (If you have any other bag suggestions, please throw them my way.) I want to suggest alternatives to his fanny pack to him, but I don’t want to be mean and insensitive.

Am I being overly shallow and insensitive? Is this something that I can talk to him about, and if so, how do I bring it up? Would you be offended or hurt if your SO felt the way I feel? Please tell me if I’m being a horrible gf. Any advice would be greatly appreciated, thank you :)
