Long, flowy multicolor criss-cross back, maxi dress

The dress has multi-color flowers all over it with a white base. There is one slit on the left side of the dress that comes up to your calf. Has only been worn a couple of times. There is a little triangle cutout right below the 3 buttons on the front. Spaghetti straps are adjustable and crisscross in the back. There is a slip in it that comes down to your knees and is a little noticeable. The last picture is how the dress looks on.
