On the cover of Distinction we have a:
Strapless lastex swimsuit, shirring at top and shirred pants.
As you can see, it's a fairly structured garment. Though we aren't given any details, it's clear that a lot of internal scaffolding was needed to hold the swimsuit up and mould the wearer's figure into shape. Lastex had been introduced in the mid-1930s, but was only just becoming popular for swimwear. Cotton was another popular material for swimsuits in the 1950s, and nylon was starting to make a splash (first used for swimwear in 1956).
Distinction was a bit of an oddity of a magazine. Published in Sydney between 1948 and 1972, it set out to describe what was in fashion with few words and lots of pictures. It carried no feature articles and no advertisements, but sold a few dressmaking patterns through its pages. Its pictures were largely uncredited (which makes me wonder whether some of them were pirated from other magazines). While it's a great reference for mid-century fashions, I'm left wondering who was its intended readership. Perhaps it was aimed at people in the rag trade looking for designs to copy?
Anyway, here is some of the magazine's advice to readers in the Australian Spring and Summer of 1957-58:
Waistlines have moved again; this time to a position 2 or 3 inches above the natural waist, demanding attention by high placed belts, wide cummerbunds, draping and short jackets...
Shorter sleeves will play an important role for warm weather practicality. Capelet and balloon sleeves vie with the dolman, set-in and unmounted styles for popularity.
Hemlines for street dresses remain approximately the same position, perhaps an inch longer, but certainly no more.
More detail is given to skirts, they look freer and easier, but it really isn't so—they are still basically slim. This illusion is created with pegged skirts being curved at the hipline but tapered below...
The mood for absolute femininity is expressed in fashion by the use of soft clinging fabrics...
