A rare and collectible dress -- a vintage 1950s rose print Dorothy O'Hara dress. I believe the fabric is an AAA (Associated American Artists) rose print (the rose print fabric on the Sex and the City red and white roses halter dress worn by Sarah Jessica Parker). While the fabric on this Dorothy O'Hara dress isn't marked, a fellow dealer (emersonmaevevintage) who specializes in novelty prints helped me compare it with marked versions of the AAA rose print fabric, and it's the same pattern.
This Dorothy O'Hara dress has a gathered bodice, bustle back, back zip, and underarm gussets. The rose print fabric is cotton.
Bust: will work for up to around 36", but looks good on my 34" dress form because of gathered nature of bust
Waist: 27", but would work for 26-27"
Condition: Very good. A few very faint faded spots on the front skirt--they're barely noticeable. (See last photo for an example.) Dress presents beautifully!
