Everyone under 4 feet tall has cowboy boots in the house, so I can't figure out why they didn't want to go as a cowboy and cowgirl? We would get a different shirt apparel. We could even go with a jean skirt.
Although I think those are great pink cowgirl jeans. (Sure she lost her diaper butt filling up the pants, but still.) K, so Halloween only comes once a year, can't waste it on ideas that aren't yours, but why doesn't anyone want to play cowboys and Indians?
Its like Woody found out, its all about space, and robots.
There is always next year... even though she has been wearing those boots for a year, she still has at least another year before they fit.
