R.M. Williams Longhorn Women’s Long Sleeve Button Up Fitted Western Shirt US 6

This is an unused women’s R.M. Williams Longhorn SIim Fit buttonup long sleeve western shirt in a red, green and white plaid pattern from 2010. I purchased this in Australia from a RM Williams store for a horseback riding trip but it went unworn, and has been in storage so it’s in perfect condition. It is an AU 10 which is a US 6. Pit to pit: 19 inch Length from shoulder: 26 in
