Dreamband - The Elf! (Patreon)

Originally I had an even skimpier dress on the Elf than this one, but this outfit is simply bright and full of joy.

*Slight spoilers*

The pink haired version is my pick, with the blond a close second. This Elf form has also inspired me to change the ending a bit, from the main character simply changing forms in front of their friend when they first meet up again, to something more Cosmomagician in style.
