The bust is done.
I was nervous my Tivoli wouldn't fit. So I finished the bust and put it on scrap yarn and tried it on. And it's alright. Phew. There's a tad bit of room, so i think I could even have gone with the smallest size, and I think I might do that with the next one (yes, I want to knit another one!)
This one is fine though, I think. We'll see after the waist decreases. This pattern is so quick and simple, I'm enjoying it.
