I wondered if anyone else had noticed this? I'm an 8 or 10 in tops, (depending) and some recent orders (blouse type summer tops) from Boden in an 8 are huge. I saw that the same tops came in a 4 and 6. (These are UK sizes, not US.)
The garment measurements fit the 'new' sizes too, meaning a 6 might be better for me - unheard of!
