Drawn by Izumi, these are the sketches of the beach outfit Zoey will be wearing on a planned beach trip to the Southern California coast common to all routes; I'll keep updating with more refined versions of the art as I get them.
You can spoil yourself a bit with the design document we gave Izumi if you want, but this is the first of 3 outfit reference sheets she's drawing for Zoey's outfits because they'll greatly simplify making the final sprite outfits for Myumi or TiltSHIFT.

It's inspired heavily by a blend of Arknight Ch'en's "Female Tourist C" and "Ch'en the Holungday" skins (I guess that's the right word, but the former is only a sprite and the latter is an alternative operator form?) and features a lot of moving parts/accessories that'll change, be removed, or added throughout the day, such as:
Given the complexity of the outfit, I'm positive that clear references for the outfit and its various states was the way to go as they'll speak a thousand words more clearly to Myumi or TiltSHIFT and bridge the language barrier than my own words could.
