I use a bike poncho, it covers the legs, too, and limits sweating because it is open underneath. Decathlon sells them for cheap, and them works. There is also normal colors, but I prefer to be absurdly visible (I want to see who says "I didn't seen him π)
Every time I use it, I'm amazed I'm dry underneath (the face gets wet).
In any case, even if I don't wear it, I'm unlikely to get soaked, when rain is not that strong. We are not made of sugar!

l second the socks, I always have one readily available in my bike bag.
And since one particular thunderstorm a few years bag: also a fresh pair of underpants. Though that might be overkill for most...
With some nasty weather, I had used a kind of ski mask (called Sturmhaube in German). But at some point I realized it is better to take them off when you enter a bank to fetch money π
