Corduroy Birthday Jumper

I've been spending oodles of time online trying to figure out how to make Z's birthday dress/jumper after buying fabric without a plan...we don't make it to the store that often.  So I have corduroy elephants and paisley purple corduroy that I want to make tea party worthy (doesn't sound like a great fit, but it seemed the wrong season for light weight cotton).

I have Alice in Wonderland style dress in mind, but I'm not sure I can pull it off in corduroy.  I think I'm going to make something like this skirt from The Mother Huddle blog with some slight modifications.

Hopefully, when I'm done, the yoke section won't be so long, the front will be flat, and there will be a trapezoid bib attached with criss-crossing straps in the back.  Wish me luck!
