Spot the difference

If you want to change the look of your LBD for Christmas why don't you try this idea?
I started out with this plain velvet dress

and used a bit of sheer black fabric with silver spots on to make some ruched sleeves.  I also cut out a couple of circles of the same fabric and pinned them to the dress behind a diamante brooch.  

I only wanted a temporary change so I tacked the sleeves in for easy removal, but of course they could be properly sewn in.
