I'm going to do something crazy with my coworker who wants to go to a concert of a singer that she loves, that will be held in Germany. We will travel during the night by bus, get there in the morning, visit the city, go to the concert in the evening and get back to Italy next day.

I was even thinking to bring one only outfit. After all it is one and a half day.

Or, bring a comfy outfit for travelling and going around (casual warm pullover and stretchy blue jeans) and something dressier for the concert (prettier pullover and new navy pinstripe pants)? Shoes will be my blue velvet slip-ons.

What do you say? Suggestions are welcome. Thank you!
