I lied. My drawings didn't get posted last night because I didn't have time to finish them.
Here they are now. I drew a front and a side view, just so you could get a better idea of the shape of the dress. I also outlined all of my lines in black pen. Normally I wouldn't, but my scanner sucks at picking up pencil lines. Please excuse some of the odd colouring and such, that would be the fault of my scanner.
When I think of air, the first thought that comes to mind is that its very cold, sharp, and harsh. (too many winters in the Midwest are to thank for that.) So, I decided to draw a dress using only blue and silver, as both are cool colours, and make everything very angular, and, well, pointy. It's an asymmetrical trapeze dress.
