Vintage Helga 1950's Peplum Sequined Evening Jacket Pop Art Fitted New Year's

Vintage Helga 1950's Peplum Sequined Evening Jacket Pop Art Fitted New Year's in very good condition, there are a few picks or snags on the bottom side of the sleeves where your wrists lay on things. sequins are very good reminds me of a toy soldier perfect for evening formals PLEASE look at measurements as this is very fitted and there is no size that I can find. There is also no fabric tag. My opinion is this would fit a modern day small. I dated this using the vintage fashion guild
