Because sequins doesn’t always equal elegant, one can also wear a sparkly skirt without heels and make it casual with a t-shirt, a bit like the “jeans and jacket” of the ’80s!! I loved this look I saw yesterday on a woman passing by: t-shirt, sequins skirt (very light and with a short, not excessive opening on the side) and a pair of Converse. But of course a pair of sandals could be ok too, as long as they were not heeled and had a casual look to them.
Have fun!
