You are looking at one vintage SUNDRESS. The brand is Tumbleweeds of Phoenix, AZ. T is no size tag but, I would say this is a women's medium. The fabric appears to be a cotton blend. Has buttons all the way from top to bottom on the front, sweetheart bodice and non-adjustable straps. I would guess this garment to be from the late 1970's. Very well constructed piece! Measures 18" armpit to armpit, 36" waist, 52" hips and 35" from bodice to hem. Mid-calf length. Very good condition--gently worn. Feel free to ask any questions or see more pictures. We do combined shipping and we ship fast! Check out all the antique and vintage clothing in my eBay store.
