Perfectly sweet, sassy or sophisticated. All depends on you!!
Size: One Size, Color: Black
Bought it for my daughter for Christmas. She's 5'3" and wears an assortment of styles. This goes with them all and fits her perfectly! Super cute but also classy and sophisticated with the versatile straps. The quality overall shows she can use it for a long time, too.
