I Have to Find This!

Growing up, my mother had these pillows with this black, white, red, blue, yellow block design. I absolutely loved these pillows and when I got my first apartment she gave them to me. This October I was at a party and I saw this girl with the pillow pattern on her dress. It was super cute. Now I realize that the pillows and this girl's dress are copied off of the vintage Yves Saint Laurent "Mondrian" dress which was designed by the late designer in 1965. I have to find the knockoff dress that this girl wore at that party. It's a must have for me. The picture on the left is the original dress. The knockoff was a short, form-fitting dress, with the same pattern, but long black sleeves. Worn with black leggings it would be beyond chic! I have to find this dress! That is my mission today. UPDATE: Of course, knock-off giant Forever 21 made a similar dress (pictured to the right of the original dress). Unfortunately, they no longer carry it. I'm gonna keep looking though.
