The cut and fit on these trousers is incredible... incredible quality, as you would expect from Victoria Beckham.
A good fit for a UK12... the label size says UK10, which would also work but with a slightly more 'masculine' loose fit. They're relatively high waist + slightly cropped (based on a height of 5'7").
A wool/ viscose/ elastane mix. Fully lined in cotton.
In excellent condition.
