I have decided to treat myself to a pair of sunglasses. I do not want to spend over £250. I suit square/large cat eye shaped glasses. I am confused by all the different brands and would appreciate recommendations on where to shop and the best brand for luxury but also safety for my eyes in the sun. I have seen there are small sunglass hut shops, anywhere else? Happy to shop online too as long as I can return if they do not suit me.
