Vintage R & M Richards Dress

Beautiful R & M Richards dress. This is a dress from my mom’s closet, so I’m sure it has not been worn but a couple times. The size label is missing, but the measurements are 26” armpit to armpit and length is 50”. I’m su e this dress is a women’s 22 or 24. It’s a beautiful dress in earth tones and it’s a very flattering style. Thanks!
