Unique homemade white rabbit Halloween costume

This white rabbit from Alice in Wonderland costume was a big hit last year. I threw together a royal blue blazer (Jcrew-size 12) with a white dress underneath, bunny ears and a tail. I improvised with a compass on a string as a timepiece necklace, but have since acquired a proper one from a costume store so whoever wears it next can be more authentic! White dress not included. You can also wear a white top and pants, etc. Costume bundle includes blazer, ears, tale and timepiece necklace (new and unused in packaging). I typically wear a size medium in tops, but the blazer created a perfect oversized look over the dress I wore it with. Last photo is of the costume I originally drew inspo from.
