Women’s 3/4 sleeve 6 button top, woven material. Possibly size 18, no inside tag

This woven women’s top has a v-neck and 3/4 sleeves. Tans, rust, cream and black colors, 6 tan buttons down the front. No fabric or size label but I wore it at size 18. Fabric may be woven rayon and is semi sheer. Good shape.
