a girl or woman who is dull and wears old fashioned clothes;
a dull, unpleasant and unattractive person,

a group of frumps
My cousin is a frump and she hasn’t got any boy-friends.
It is found out that all most all the women take a down turn at the age of forty and so and show the obvious signs of being typical frumps.
There are several TV shows and websites with videos on the Internet that advise those women who turned frumps after having a couple children to stop being frumpy and get back in shape for their self-satisfaction and, more importantly, for keeping their husbands from straying!
It seems that people, especially the girls, in show business must always look gleen, otherwise they will be stamped ‘frumps’ and the ratings sink down like a stone in a pond.
