Dark teal short dress/Tunic

This is a cute piece originally bought at “M” boutique. It’s a dark teal colour and can be worn on its own, or in colder seasons with a pair of leggings underneath. There is an elasticized waist, pockets and an overlap ( like a slit) on the skirt part. It’s 100% polyester, but feels like a heavy crepe fabric. The tag says dry clean only, but I’ve washed it in the machine on delicate with no difference to the fabric. It is gently used but no signs of distress.
