A festival look and would probably look better with a pair tan lace-up sandals but I don't own any. I had 2 bad experiences with such sandals. A piece of broken glass jumped and got between the sole of my sandal and my foot! My foot bled profusely and I was really worried that I might caught on some weird diseases from the broken glass.
Years later, I went on a summer holiday in Barcelona wearing a pair of gladiator sandals. BIG MISTAKE!! I had to live with the odd tan lines on my feet for a few months! Hahaha.
But that being said, I quite tempted to get a pair of lace-up sandals. Obviously, I haven't gotten any wiser over the years. Hahaha.
