Sewing is a Pain - Especially when Sewing Obscure things...

The most annoying thing that happens while trying to create a costume is being unable to find the right pattern (so far as I have learned).

I am making a Sakura (from Tsubasa Chronicles) costume, but can't find any patterns (for her shoes) that are similar (see first picture).

Any suggestions would be greatly appreciated.

^-^

The pictures following this are some reference pictures I used for the costume (which I haven't started yet, I am just looking).
