Do it! Strictly functionally, human shoulders are naturally a load-bearing structure, and suspenders are thus the most intuitive way to hold up pants. Belts work by increasing friction between your pants and your torso, and (thanks to Lagrangians and such that I don't remember how to derive) actually accelerate pants droppage, for those of us who have been GOMADing unnecessarily. They really only came into fashion when the vest that covered them more or less went (temporarily) extinct, which coincided with a whole bunch of guys coming back from WW1 having discovered the belt as part of their military uniforms.
I've had friends who treated suspenders like coming out of the closet, wearing them for only a few hours a day under a sportcoat, gingerly exposing them for a few seconds at a time, etc etc. Totally unnecessary; just make sure your first pair is a neutral blue/grey/burgundy affair that matches everything, since the obsolete "rule" for suspenders is that they're supposed to be the vest and thus are an undergarment; that's obviously no longer true, but maybe save the fashion statement (Trafalgar Ltd Editions, a la Niles Crane) for your 3rd pair. Technically, now that suspenders are to be seen, the leather loops are supposed to match your shoes, but only goobers care about that and they're too busy being fedora neckbeard m'lady weirdos for their opinions to matter.
Everyone giggled and pulled on mine on Day 1. They were boxcloth though and not stretchy except for the back piece, and I am still feeling the long-term effects of that day's wedgies.
Remember guys, it pays to be about 10% spiffier than your peers, and well-tailored suits make everyone look better. I've recently expanded this idea to casual, and have been having a lot of fun at it. What I mean by that is, suits are awesome, but they don't always scale down as hard as you need. For example, for offsite meetings at the bar or on weekends, there's not a lot you can do to dress down a suit besides losing the tie and adding a louder shirt. The fabrics also tend to be more delicate, which gives you an extra thing to worry about if you're walking around Disneyland or something. What
does scale across a wider range, I've found, is a well-tailored blazer/sportcoat in a cloth/pattern slightly less formal than your standard navy or gray worsted suit jacket. I usually use a cheapo navy cotton one from J. Crew Factory that pairs with everything from khakis and a polo for the weekend to gray dress pants, white shirt, and tie for when a suit is just a haaaaaiiir too formal, e.g. at an academic get-together, except in the rare case where I'm one of the speakers. Since it's cotton, it's much lower maintenance and runs cooler during the summer. That said, given our proclivity for barbells, I get the feeling guys on this forum lean more towards the classics, so you can't go wrong with a standard blue blazer with gold buttons. That thing's basically a suit jacket, except perhaps cut a bit shorter and with patch pockets. Looks great with everything except you miiiiight start running into trouble with jeans.
Related: The other day, I walked in on Vic and his son putting an awesome camel-colored 100% cashmere sportcoat with brown plaid and blue overcheck onto an older guy. Looked something like this:
This is a great example of why this whole smart-casual thing has really grown on me. The pattern is pretty loud, too loud for me to wear as a suit (though guys with bigger balls might pull it off), but for a sport coat paired with quiet light-colored pants, it's a great way to add a bunch of color and depth that can pair with any number of pants, ties, and shirts, all the while looking super casual and relaxed, as opposed to classic blazers, which again are very useful but can bring to mind the image of a rich asshole....when I'm actually a poor asshole.
