Help dating Victorian/Edwardian piece made in Hong Kong

I purchased this gown and matching coat from the home of a retired antique store owner. The owner was moving into a retirement home, and her daughter was selling her collection. Unfortunately the daughter didn't know if this piece was authentic from the 1890s-1910s, or if it is a costume.

The fabric seems to be wool and is quite heavy and well-made. The jacket has hooks and eyes as closures in the front. The back of the dress has a metal zipper going from the neck down to the upper back, then hooks and eyes going sideways, and another metal zipper than goes down the back, more off to the side. The zipper is what gives me pause, although it could have been added later on. The zipper brand is Talon (which went out of business in the 1960s).

The inside of the coat has a label of a custom tailor, K.Y. Lee in Hong Kong. I haven't been able to find any information about the tailor, but the street from the address has been around since the 1890s.

Do we think this is authentic 1890s-1910s, or a costume from the mid-twentieth century?

 

What a lovely piece! But, with the zipper, I would say more recent and to resemble an antique gown and coat

 

It’s a beautiful dress but it’s not reading authentic turn of the century to me.

 

It appears to be a garment made for a masquerade ball or costume event, fancy dress ball, etc. But it is made with such wonderful tailoring, it goes beyond a simple "costume". Outstanding. Not antique, but wonderful nonetheless.

 

it's late 60s, probably... that popular Juliette look then. NOT actual Victorian.

 

A very high quality reproduction, and perfect for a reenactor!

 

Possibly made to co-incide with the "My Fair Lady" film release and the following year or 2 when it was popular for costumes and masquerades. It is Edwardian style, not Victorian, and seems right for about 1910-1912. The label, tailoring techniques,and Alaskine fabric (as Maggie mentioned) is also right for that time of the 1960s. Since it a "costume", my guess is that a wealthy lady had it made up for herself for a special costume occasion. Just a hunch.

 

this might help? this picture, which shows KY LEE tailor in hong kong, was taken in 1964

 

Just to clarify:
Talon zippers are still being made to this day. The company has gone through several changes of ownership (the first in 1968) but the name Talon has been used on zippers throughout.

EDIT: Yikes, I didn't realize this was an old thread brought forward by builder bob's additional info.
