I need help with gear sizing

I am a guy, 20 years old, about 180cm tall, my chest circumference is 86 to 93cm on a full breath out and in respectively. Until now I was using a 661 evo compression jacket (img 3) in a size small from ~5 years ago that has obviously stretched.

I was considering either of the Leatt stuff in img1 and 2 but for height I am between L and XL while on width I am on a small.

I contacted Leatt and the recommended going with a plastic/whateveryoucallthat chest and back protector (img 4) that is more adjustable but those usually don't have shoulders, from what I hear are not as comfortable and I also don't like the look of wearing one of those.

I would like some ideas on what to do here, I also have the option to trim the shirt type protectors at a sewing store if that would help

Thanks a lot
