Coat Pattern & Ideas6
I think I want to make a coat that is pretty classy rather than being too cutesy. So this is the general shape I've seen for a typical Lolita coat. It seems they are mostly double breasted, are very flared (to fit your skirts under!) with large collar and cuffs. I quite like the cape as well.
So, pattern-wise I've found this: Simplicity 4033
I'll be first to admit that those coats look pretty bad, especially the one on the left... but the outline is almost there. Imagine the bottom one with a bit more flare and a rounded collar.
