I like the design ( like wearing sunglasses on head) but the sizing not great for me - the top bit sits quite square on head and leaves a little gap on either side. I have to arrange my hair to try to fill the gap. Comfortable though . I think the other size, according to reviews, would be too small - I would sany I have an average size head! Shame it doesn’t fit exactly as I had hoped but need to try make it work because of the cost and as an accessory no refunds! Delivery was pretty quick.
