Day to Night Outfit

Day outfit: I am wearing my onsie underneath a stretchy pencil skirt with tights and with a cardigan over it to make it appropriate for work.
Night outfit: I took off the pencil skirt and the cardigan and could add some statement jewelry to make it dressy for an evening out.

How do you like my transitional outfit? Does it work?

Disclaimer: My hair looks crazy because it was the end of the day, please excuse.
