Narrowly missed a pair of size 12 in the online sale by not buying when I first saw them on Friday. Does anyone know if the sizing is big or small? I'm usually pretty reliably a 12 in most high street brands (ASOS, Top Shop, Oasis etc) so am wondering if the 14 will swamp me or if I should risk cramming myself into a 10. Or just learn to online shop without dithering.
