Vintage 1970s Thea Porter Dress Black Brocade Cotton & Lace Balloon Sleeves

From the queen of British boho styles of the 70s comes this dazzling frock in a semi-sheer, gauzy, black fabric featuring a brocade embroidery of ivory medallions with burgundy red squares in the center. The collarless, V neckline plunges into an empire waist seam from which an ankle length skirt descends and features a wide cream lace panel at the hem. The cream lace is echoed in the central sections of the voluminous sleeves that have elastic cuffs. Closure is a zipper at the center of the back.
Note that there are shoulder pads for adding pouff!
Lined around the neckline, front and back.

Label: **Saks Fifth Ave. Made in England**
Note that there is no mention of the designer THEA PORTER in the label. I think this is either because if was a separate label that the owner likely removed for whatever reason. If you compare this dress and its intact tags with others like this online, you will see that the "100% cotton" and the "Dry cleaning essential" tag matches to ones that do have the original Thea Porter label.
