In need of advice, fem but need binding help

So I'm demigirl (for those unaware, it's where your gender is part girl, part something else. For me it's part nonbinary). And I get gender dysphoria. Specifically around my chest.

I'm a C cup. Not large, I know. But I've been thin all my life, so when my chest came in...they came in sized for the wrong body. I'm already saving for a breast reduction so I can go down to a A or B

So I get anywhere from general discomfort to wrong bad wrong with my chest, especially around the bounce and size. I wear high-impact sports bras all the time. Have for a...year now?

But those bras have limitations.

I can't wear tank tops (the straps show, and if I don't wear a bra I can't deal with the size), I can't wear certain dresses. God help me when it comes time for Fancy Dress Day (aka prom). Swimming is...annoying (why can't I find supportive swimware). I also wear my bras so much they're...starting to strech out. I also sweat a lot in the summer because of how thick the fabric is.

and so recently, I've been looking into tape. I don't need to be fully flat, I just need to Lessen the Chest, especially because I've been having a kind of dysphoric week.

But I can not, and I mean CAN NOT, find tape guides for people that need both minimization and support.

So, I'm reaching out to the various ftm peeps out there. You guys have the most experience with binding, and I need help
