I'm after a summer cardigan style thing to wear when on holiday. Not a beach cover-up exactly as I want to wear it when walking around sunny towns rather than just on the beach. I have visions of a lovely patterned, silky or cotton material loose cardigan but don't really know exactly what to search for to find such a thing. I adored the red and white shirt that one of the characters in the night manager wore (I will try to attach a photo). I think this had a collar and button but I think I would prefer something without either. Any ideas where to look? High Street budget! Thanks
