Vintage 70s Mod Sleeveless Palazzo Jumpsuit in Red White and Blue - very wide legs!
No inner labels besides dry clean only label (I hand washed upper white part). Nylon zipper on the back, works well but slower at waist where material changes. Polyester material -thin on bottom, double knit on top. Cummerbund feels more like terry.
No size tag. Fits like modern M/L: 59" total length. Pants have 25" inseam from dropped crotch, you can see it was good length on 5'8" mannequin, 29" high waist at red cummerbund, 44" hips, 38" maximum bust (19" across underarm to underarm), 15" shoulders. Mannequin is 5'8" XS - outfit fit well as shown, would be more fitted/fit higher in top on M or L.
Flaws - pencil eraser size hole above hem, pen tip size hole further up from hem on same leg - see closeup photos.
