Jeans are not good for riding, they soak up water, get very heavy and take ages to dry. Hiking style polyester or poly-cotton mix is much better in every way.
You should only wear waterproofs when it is raining, they are too clammy otherwise. A windproof, non-waterproof jacket or smock is much more comfortable.
Look for bright colour, reflective piping, pit-zips, fully vented back and a front zip with poppers so you can ride unzipped but closed. (modern waterproof zips have no poppers).
I am less fussy about rainpants, any breathable waterproof with zippered lower leg and velcro cinching.

Fenders are a must for clean commuting. SKS chromoplastic bolt-on are the ones to fit.
