I am normally a UK size 8/US Size 4 in most brands. However, is it me, or does the KM sizing run smaller than other brands? I have a bust of 35 inches, waist of 24 and hips of 37(due to my bottom)- roughly a small hourglass according to my calculations.

Which size would you recommend for me when shopping KM? I ask since the guides are a bit sketchy and due to the tightly fitted nature of KM clothing, I don't want to make a mistake again.
