Anthropologie Lilis Closet Sweater, One Sizee, Cream and Brown Mohair

Gorgeous sweater from Lil's Closet. Cream knit with brown rosettes along the bottom hem. Deep arholes, nearly like a poncho with sleeves. There are no tags so I dont know contents or size, but it feels like it has mohair or maybe angora in it, and my best guess as to size would be medium range, see measurements below.
Excellent preowned condition. No issues to note.

armpit to armpit across bust all round: 48" at rest all the way up to about 75" stretched but please remember this is a very deep armhole.
waist: same as bust
length shoulder by neck to bottom hem center: 23"
