I'm getting ready to do a bike tour myself, although not to Europe. I have a number of sporty, A-line, knee-length skirts that I plan to bring along so that I can simply pull skirt over my cycling shorts when we stop for lunch, shopping and the like. Otherwise, you might try a cycle skirt. There are some padded cycle skirts that might work for you, too. I already have more than enough padded bike shorts, so I'd prefer to just use the shorts and skirts that I already own.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
