Vintage 1960s Sue Brett Floral A-Line Dress

Scoop up this adorable floral A-line dress that I nabbed at a local vintage market. Likely around a size 0, potentially close to a size 2, but no sizing on the tag. I'm a size 4 and it's too tight (for perspective). Length is about 37.5 inches. Adorable detailing with the button-up back (as well as a zipper on the lower-half/skirt portion of the dress). It's a Sue Brett vintage dress, likely from the 1960s. Doesn't fit me, unfortunately. It's in good condition, without any noticeable stains. A tad delicate around the seams, as per the era/age of the dress, so needs to be carefully put on (again, as per most vintage dresses), but no tears or rips.
