Smock tops are 'in' at the moment. I can remember when the only time a person would be seen dead in a garment of this sort would be when she was pregnant. Actually showing your 'bump' in revealing clothes was distinctly frowned upon.
Anyway, being a dedicated follower of fashion, I bought a couple the other week, thinking that they'd at least be nice and cool for the summer (I'd have done better buying a pair of wellies and a raincoat).
Then there was a revelation - an unexpected reflection in a window showing me wearing what looked like a small tent convinced me that they would be promoted to gardening clothes; non-restictive and comfortable, oh yes, and cool.
Small, round women shouldn't wear smocks unless they're pregnant.
