From the seller:
THIS IS A METICULOUSLY MADE SILK CHIFFON BLOUSE. THE BLOUSE IS MINT AND BETTER SEWING WILL BE HARD TO FIND . I WOULD SAY THIS FITS A 38" BUST. THE TIE CAN BE CLOSED AT FRONT OR BACK. IT RETAILED
IN STORES FOR 475.00...
From Me:
For the record, if anyone paid $475 for this, I'd wondered what they were smoking and get them to do it again so I can sell them oceanfront property in Arizona.

The lady with the plaid skirt has on a blouse similar to the extant one. This is from April 1914. I actually think the blouse is from a little bit later (1916) based on it's length but you can see the start of the fashion here.
