1979 Outfits-Day and night fashions: Rock’n’Roller, 44201.
As you can see the Rock’n’roller in the brochure was only a prototype and came out in different fabrics, both the jumper and the trousers.
As shown with variations of Rock’n’roller in the 1979 Sindy outfits folder at TLSM.
On the photo above you can see two versions of the trousers for this outfit (navy blue and white cotton) and two versions of the jumper (cotton and polyester fabric). The stripes could apparently be used how ever, as you can see on the right bottom jumper (the right sleeve has the stripes up-side-down) and on the two cotton jumpers on top (both their sleeves in the middle of the page have the stripes up-side-down, compared to the jumpers’ front pieces).
