I see this bolero/jacket combining several historical eras as well as crossing a line between multiple styles of Lolita and Neo-Victorian. Definitely a treat, this one, although the contrast between that interesting pattern and the solid black trim is possibly a bit harsh. Then again, it is surely less severe as part of an entire outfit with perhaps some other black pieces (as presented on the site). Quite elegant, yet perhaps not entirely down the EGL/EGA alley due to the pattern.
