just offhand I think denim mini, cowboy boots, pigtails, cowboy hat, and s/s button down plaid top tied under the bust to expose the belly.
I agree with everything, except, instead of a denim mini, wear some sawed-off, Daisy Duke shorts! Afterall, that's why those shorts are called Daisy Dukes!
If your gonna go as Daisy - think the original - NOT Jessica Simpson. Daisy Duke Shorts, a flannel top or at least plaid top (tied at waist) and boots!
