Yes & no. You can get a full leather suit or go with leather jacket & separate leather overpants, your choice. You can also get vented leather or textile, just make sure it's armored to a high degree. Shoulders, elbows, hips, knees, and shins should be protected. Asphalt doesn't care about your fashion sense. Are your boots armored, with plates on both sides of your ankle? Lots of little bones in there that could get turned into mush if you don't protect them. Got a decent full-face helmet? Sliding down the road face-down won't do your looks any good if you've got an open-face or beanie helmet.
I've been riding since 1978 and my gear has evolved over that time, from an open-face helmet, ski jacket, jeans, and sneakers to hi-viz Schuberth modular helmet, Klim textile armored jacket & pants, BMW Motorrad boots, and Helimot gloves. I'm better protected wearing that gear than I would be wearing jeans, even armored Kevlar jeans. I'd rather be well-protected than try to be fashionable, etc.
Be safe, ride ATGATT.
