Ok I'm looking for a Dress/attire for my Assistant and would like for her costume to look like it was from the early 1900's also a tuxedo would not be a bad ideal either. anyone know where one can acquire either one. Don,

The early 1900s crosses a broad fasion selection. Could be be more specific? You might mention the style era, financial status of the character, ocupational representation, region (ie Western US, Eastern US, Europeon, etc.). For period costuming, beware the Tux, they are a modern creation, though we are talking modern as in the 1910s. Unless of course you mean Tails, which are a different matter entirely. For all modern formal wear you can't get any better than an Al's formal wear.

The type of fashion I'll like would be something worn up on stage for a female Magicians asst. it can be a dress or body suit. maybe European and yes to the tails on the tux. also anyone have a link for this AL's that was mentioned.

Do what any clothing designer would do- head to the library and find a book on 1900's fashions. (This info might also be on the internet if you search carefully.) From there, you can determine which looks you like best and which will be most useful. (From my quick search, hoop skirts seem to be in vogue- lots of possibilities with hiding stuff in there, though it won't work well with 'box' illusions.)

You might need to go to a costume shop or specialty theatre costume shop to get what you need, or have a seamstress custom-build it. Keep in mind your assistant will probably never forgive you if you make her wear a corset...

A Tux Shirt, bowtie, vest, tails, a pair of bloomers, a pair of fishnet stockings, and a pair of high heels might be what you are talking about.

Do a search on re-enactors on the web. If you're looking for early Twentieth Century attire then you will be looking for Late Victorian or Edwardian fashion.
The Tuxedo made it's debut in 1886 so you'd be safe wearing one as long as it was of the appropriate cut and style. As for womens fashion. Hoops were pretty much a thing of the past by this era. Long skirts and jackets with mutton chop sleeves were all the rage. And big hats with lots of bows and feathers.
You will pretty much have to have everything built custom as the ready made stuff is either hideously expensive or made poorly.
Corsets for the women are also a must as the garments wont fit correctly without one.
The BBC series Lost Empires would be a good resource to look at as it is set in the Vaudeville Houses (Music Halls) in this period.

Payne Thank you. anyone seen the 1953 Movie Houdini. where they are doing the Metamorphosis/sub trunk the Costume that Houdini's wife is wearing is it from that time period.

Probably not. Movies from that era weren't known for their historical accuracy. Especially where womens hair, makeup and silhouette are concerned
