The collar has a button at the very top, very fitted on my mannequin, approx 12. 5-13".
Condition is good with overall fade, moreso across shoulders, underarms are discolored, the white in this area is more ivory. There is also a pen tip size hole by the front hem, see closeup with my hand holding up hem.
