I LOVE that pattern!!
I might have to try that myself...
I'm a beginner too, and I can safely say that pattern does not look at all difficult for a beginner. Not at all!! The only tricky bit might seem to be the ruffles, but that is only an illusion. Use these videos
to help with knitting through the front and back, and you'll be fine! Plus, there are great folks here who'll help if things get tricky.
Make it! Make it! You can do it!
