Described as having a style defined by contrast, Jocić mixes opposing colors, fabrics and forms.^[5] In order to reduce fabric waste, she uses draped layering and precise pattern cutting,^[5] as well as following the principles of origami paper folding.^[5] The fabrics are folded into 3D shapes creating a sculptural effect.
