If you look on the girlscoutshop website, you can see current uniforms. The brownies have blue shirts, brown shorts, vests, sashes, beanies and a tie. The Cadets have shirts, vests and sashes.

Otherwise go with option 3. People may want to do a picture of an older time period. What I see of the current stuff, it's not that different from what I used to wear. We just had more things, like long pants and jumpers.

I've spent the better part of the morning looking at the girl scout shop website. As far as I can tell, the sash, vests and tunic are the only "required" girl scout uniforms.  They do have pictures of them wearing matching skirts, pants, and socks, but they're not really required.  I found a brownie scout uniform and a cadet scout uniform, neither of which came up on my earlier "friendly" Google searches, vilters.

I hate khaki and brown.
