Abstract Dress - Size L

I purchased this dress last Fall and have never worn it so I am now reposhing it. A very fun and colorful dress/tunic with beading on the front. Photos 6 and 7 show the side slits which I didn't know were initially there. It would be so cute with black leggings! There are no size tag, fabric content, or washing instructions on it. I believe it's rayon but I'm just guessing. The last photo shows the measurements.
