It would be cheaper since most (or all) of us, do have at least wearable pair of jeans.

But some/many of us don't (or haven't in ages) cycled in jeans, it would be a challenge. Or maybe it's already challenge because your jeans are quite tight/low slung. Then we have this virtual ride over 1 wk. and post evidence of jeans ride. 1 wk. gives us lot of time to choose time/day.

If showing your face / too much of yourself is too much, just even a photo of jean leg on foot pedal.

Ok...Hallowe'en costuming is abit much..for those of us who aren't going to any Hallowe'en gig in town.
