Vintage satin shirt with trim and shoulder pads!

There are zero tags on this shirt, so I don't know what the super slippery soft fabric is but I believe it is satin with a lace trim. It's so cute and flattering, see last picture for size ideas, I usually wear a M and there was plenty of room! There are very thin shoulder pads in this item and they are fabulous, they elevate the whole item. No discolouration. Honestly I think this was originally made to be an undershirt but it would go with anything! If it doesn't sell I'm keeping it forever!
