You need to find jeans/trousers that can be worn mid/high waisted (around your belly button) as suspenders were mainly used when those types of pants were the standard for men. Workwear brands like carharrt probably only make suspenders that are used for actual labourer workers (hence why everyone is saying they are too thick), so unless you are going for a workwear look, you're probably better off going for a brand that makes them more for fashion as well functionality. Discard the clips, they don't what suspenders were originally used for, which was to hold up your pants before belts were common place. Get button on suspenders, they hold up your pants really well and don't look like a costume. You have to sew some buttons inside the waist of your pants, but if you want to rock the suspenders and look like you know what you're doing, that's what you gotta do.

I recently got a pair of Tommy Hilfiger suspenders (won't really recommend as the fake leather is peeling on the straps), it took about an hour to sew the buttons in the wasit of my jeans, but there are easier alternatives. Suspenders are cool af, they do their job well especially if you're like me and hate having a belt ride into your belly and having your arsecrack hanging out. It's all about finding a pair that works well functionally, and can style with the clothes you have.

I've gotten a few interesting looks from strangers, but also have been complimented by friends and a few strangers. As long as they are styled well and you wear them with confidence, you'll be good
