My biking clothes are now almost no different from my everyday clothes- except for wearing either chamois or non-chamois.

I always used to wear black leggings or capris anyway- even before discovering biking.
Now if it cool for everyday I wear wool leggings, maybe a short skirt, merino tops and wool jackets, hiking boots, etc. If I'm going biking I'll just take off the skirt and put on chamois tights and maybe add a screaming yellow vest or windbreaker.
In summer it's everyday black capris, perhaps a short skirt, tank tops or loose cotton tops and sneakers. To go biking I'll change to chamois capris, lose the skirt again and throw on a screaming yellow top of some sort.
The stretchy black tights/capris are the basis of most all my outfits, biking or not.
It's all slowly morphing into the same look. Luckily, I work at home and so I don't need to conform to any office attire rules.
