My husband was supposed to be getting me a lovely top from The White Company for Christmas. However, he's left it so late to sort it out that they are out of stock aprt from size small and extra small. I'm usually a size 12. Just wondering whether I could get away with a size small! Does anyone know how generous (or not) the White Company sizes are on womens clothes? Can't do links but the top is the fine knit smocked sweater. TIA.
