Nooooooo, I'm not inventive at all. My friend Melanie sent me the first dress design. I just had to get a little creative in making the breast plate and pouch.
Before getting the first dress from Mel, I downloaded the Sock Buddy efile, and all I could think of was "yeah right" - good luck getting that on with a new bird!!
Here is a picture of the first one Mel sent me to give you an idea of how it's made: http://img.photobucket.com/albums/v232/Echosmom/Sweater001-1.jpg
Mel used snap tape, but I didn't have any success in finding it so I used velcro. Both work great, but the velcro is quicker to fasten - meaning quicker to get on. There is definitely a technique to getting them on, especially with a new bird whose just learning to trust you, but it went very well considering.
The side you see with the snaps is the front with slits for the legs and on the backside you can't see the snaps so when it's fastened they are hidden (just like the velcro is).
