Description from book:

This beautiful plunge-neck top is as stylish today as it was on the “sweater girls” of the 1950s. The retro chevron pattern is very flattering and definitely a look worth reviving. Knit in an exotic bamboo yarn in a gorgeous pale pink hue, this top will be both cool and good-looking in the summer. Great with a tan, it is the perfect warm-weather piece to go with all your summer skirts and pants.

The original vintage design can be found here: Magyar Blouse (originally published in Robin No. 488, Magyar Blouse with Low V Neck in 1951).
