One of my livejournal friends reccommended Lynn McMaster's hat patterns, so I'm thinking perhaps a low crowned asymmetrical boater sized hat.
I might have to buy some hat pins, and I really need an antique button hook as the buttons on my gorey girl blouse are awkward.
I have decided that I shall wear a large bow for that outfit rather than bunches.
The university library has Norah Waugh's 'Corsets and Crinolines' and as that seems to contain the only English language 1910s corset pattern I'm going to borrow it.
There is a 1910s corset pattern online, but with instructions in German, I've done a gist translation and might have a go at it.
Ageless Patterns has fascimiles of a old french pattern (Corset Nouveau 1910) for sale, but I'd have to pay.
I've found a new resource for 1910s fashion plates , 100 of them.
I've also looked at
and of course googling designers of the period such as Erte, Paquin and Poiret.
