A 1950s swimming costume.

This is made in a bright, colourful cotton, printed with ice creams
and cherries, and very reminiscent of the bright cottons used to
make swimming costumes in the early 1950s.

It fastens at the back with a zip.  The halter straps tie behind the
neck.

This is one of those 'swimming' costumes that was meant less for
actual swimming, and more for looking pretty beside a pool, or on a
beach.
