Cache women's size 6 dress

It's a gorgeous long dress that, I wore to my sister-in laws destination wedding in Jamaica just once!! Still in amazing shape.. Costed me $300 dollars trying to sell it for a lot less.. The fabric is Satin with multi tropical colors! Mostly purple, black, white, pink and green. It has a type of zebra print in the front/side. The top part is heart-shaped strapless and I believe it has a small beading in the front right underneath the top of the dress.
