Hi there,
I'm travelling Europe later this summer and to save worrying about hair styling I was just gonna throw it back in some sort of head/hair band (not sure what you'd call it!).

Any recommendations on where I can find them? can't see any online except for topman has these bandanas which I'm not certain can be used in this way?
Any help on where to find/what looks good is much appreciated!
Cheers, Matt
