Vintage 100% wool petite Pendleton sleeveless plaid dress

Pendleton vintage 100% virgin wool green and red plaid button up dress. Full length and sleeveless. V-neck, with gold metallic buttons all the way from hemline to collar. Two side slit pockets. Matching belt. Really nice dress only worn a couple times. The tag says petite. I’m guessing a small to medium petite. The dress form is a size small.
