Front View: The pattern of the fabric appears to be gold dots(?) on a light blue background. The collar doesn't fully bend down, as it is left up a little bit. The top of the sleeves appear to be very tightly gathered.
Back View: The classic Regency back is present in this spencer. The collar seems to be a separate piece that is sewn onto the front and back.
Full Front View: The front is secured with a gold button(?) or bow(?).
