I don't know if this is an MN thing but I'm always seeing people saying clothes from brands like Boden and White Stuff are frumpy.
I don't understand.
My definition of frumpy is someone who dresses very plain and quite old-fashioned - like black or navy work trousers (probably badly fitting) with a plain t-shirt that was bought 10 years ago and got a bit out of shape, with a cardigan that is slightly too big and probably in an unflattering colour, worn with very sensible shoes like those from the Clarks UnStructured range.
Boden and White Stuff and other similar brands on the other hand sell short, colourful dresses and skirts, scoop neck tops, bright prints, high heels and colourful flats... the opposite of frumpy! But maybe I'm odd because I don't even consider M&S clothes frumpy although I think it's also possible to buy frumpy clothes from M&S.
FWIW I'm in my early 30's.
