This is something I love doing. Taking the modern and combining it in a way that looks retro. I've done it with clothes bought from the shops for a while now. But since I've started sewing I have been doing the same with my pattern choices.
Choosing the patterns that have the most versatile silhouettes that I can use to recreate the 'shape' and 'feel' of each era.
Simplicity 2249 has potential
Vogue 1186 would make some great pallazio pants
And Simplicity1799..although made longer.
I have this shirtwaister simplicity 2246
although I think 2923 has better shape
And the shoulders on this one shouts 40's to me.
There's always a plethera of 50's inspired patterns
