Noticable distress and evidence of age or use. Still wearable but also useful as a study piece, theatrical costume or fix'm-ups. These pieces are only purchased if rare, beautiful, or historically-significant.
Noted issue: two tiny holes in bust yoke. A bevy of small moth-holes in the right sleeve. Several small holes in skirt near hem. Two paint marks on skirt fabric. Suitable as a study piece or for the theater -- if not, it needs to be mended before being worn out.
