Holiday wear- How to be a stylish tourist

First Outfit: Shirt: Target/ Shorts: Please/ Cardigan: Cos/ Sandals: Gap/ Bag: Vintage/ UK-scarf: Kult/Jewellery: Vintage

I love to travel! You probably know by now. But one thing I don´t like is to stand out as a tourist, in looks or in language. That is one of the reasons I love to learn foreign languages and also reason for a very detailed packing:) As you see above I usually take basics (Jacket, Bag) in plain colors and match them with neon brights and filigrane jewellery. That way I have lots of options and little to pack:)
What are your tips for light and stylish travelling?
