My friend just made me laugh, describing how she's accidentally moved to her town's "Boden belt", and school runs are full of mums in their 40s all really skinny, toned, and with the image/style of those Boden models (slouchy trousers, etc., on skinny frames). Is this a thing? I have to say, most of the mums in their 40s everywhere I've lived are similar to me - probably a bit mumsy and filling out - and I've lived in a number of pretty middle class areas. Has everyone else heard of "Boden belts" where all the mums look like that?!
