I have brought in a range of beach cover ups, capes & kimono's from my scarf supplier for a budget pop to go over any outfit. They are very simple in design, basically a large rectangle which only has a very short 10cm side seam just under the space where your arm goes through, all hemlines and edges have been finished.
The front scoops up from the side seams to the opening and is much longer at the back, mid calf length. A clever use of this lightweight fabric with a print in horizontal stripes in varying widths alternating between soft pink and a nice blue, finished with vertical bands on the edges.
This shape is loose and flowy, not designed to be fitted, so it will fit and suit any size and body shape, I am normally a plus 20, I am 170cm tall and apple shaped, this fits me with loads of room to spare.
