Byxby sweater dress

Bought two dresses for an event last Christmas, wore the other. I have lot weight since then so this no longer fits lol never worn except to try on. Cannot find online, I believe it's got this from Jcpenny or Kohls and for around $80-90. Not sure what the neckline is called, but it's like a long dipping turtleneck? Smoke-free home, I do have pets. Sweater dress, sweater, warm, dress.
