It's never too soon to start accessorizing a suit that doesn't exist. (Is this analogous to buying adorable baby clothes while pregnant?)
I couldn't stop myself from buying this brooch on Etsy:
It may not work at all, but it called to me - and it was not expensive.
Oh, and I'm so on the fence with the plastic buttons. Though they look great, they're plastic!? Y'all have made me aware of the folly of spending zillions of hours on a project, only to cap it with plastic buttons. So...
I've called Pat of Pat's Custom Buttons and Belts (no website, but see this awesome Gertie post on the topic, which Gail so generously reminded me about) and requested a catalog. I fully intend to send her my fabric fashion scraps (at least 2" x 2" for 1" buttons) for gorgeous fabric-covered buttons. Stay tuned. (And give feedback!)
