Here are a few newspaper snippets that give you a little bit of information about Vago...
From a 1956 California newspaper article about California fashions: "Phil Altbaum's "Vago" collection featured the 'long, lean look.' This was achieved both by the use of longer skirts and also through apron-wide striped panels, which extended from neck to hem on otherwise solid-colored dresses. His 'Mancini' line did follow the empire look, but sheaths were eased via hip tucks."
From a 1957 article about sheaths: The creation, a Vago junior, featured a fingertip middy and pleated underskirt."
From a 1957 article about fashion: "...from the designers we talked to during the intermission, Louis Tabak, Phil Altbaum (Mancini-Vago Jrs.) ..."
From a 1956 newspaper: "Famous for her startling combinations of brilliant colors, her use of handsome textures in completely original designs is Betty Ingvold, designer for Vago, Jrs., for Phil Altbaum."
From a 1964 newspaper: "In the '50s Betty (Ingvold) went to the Phil Altbaum organization in Los Angeles, introduced its Vago division, was there credited with introducing the avant garde approach to California junior clothes. No longer did they look like 'little girl clothes' when Betty designed in striking combinations of aqua and orange, pink and red, blue and green. Her work contributed to this category becoming 'a size, not an age' as the trend is now described"
