Clothing shops in Europe [River Island?]?

I am going to Europe for two weeks to visit Switzerland, Austria, France and Germany. I am wondering if they have a River Island anywhere close to any of those areas. If they don't then I'd appreciate suggestions on some similar (stylish, chic, trendy, urban) clothing/shoe/accessories in France, Germany, Austria or Switzerland that are recommended.
If anyone knows of some good products that Europe specializes in beauty or style wise that are suggested that woudl be perfect. [Things such as skin care brands or little boutiques I should keep an eye out for]
I hope everyone understands and thank you oh so much!
