From the seller:
A charming 1860’s floral printed cotton antique robe that has been de-accessioned from the Metropolitan Museum of Art. The fabric has a floral pattern in shades or red, mauve and blue on a cream colored back ground. The robe is decorated with red, tan and teal blue geometric trim. It has pagoda styled sleeves and two side pockets. The armscyes are piped. It has a front button and loop closure. The robe is lined with cotton. It is in very good and sturdy condition. There are several missing buttons and some age discoloration. (See photos.). Loose fitting bust 40 Length from shoulder to hem 55.
It's probably a bit earlier - 1850's. Here are some other dressing robes or wrappers that have similar cuts:
|The original image from the Met|
Wrapper Date: 1840–60 Culture: American Medium: cotton Dimensions: Length at CB: 60 in. (152.4 cm) Credit Line: Gift of Mrs. D. Chester Noyes, 1950
So, since the Met agrees with me rather than the seller, I'm putting this in the 1850's.
