This is definitely my style vibe for a European vacation. I would call it "casual glamour" but in no way are these the only items to use to achieve that. There are similar looks at every price point.
The most important part of this set is just understanding that it's essential to pack piece you can wear more than one and in different ways. Get creative and mix and match. There are so many ways to wear your basic pieces. If you want to get crazy, you could even put your striped shirt under that red jumpsuit.
Be comfortable. Dress appropriate. Protect your poor feet because there will be lots of walking.
