Well it’s french !  so the first step is European sizing, we convert to UK sizing for you on the webshop.      Then each brand traditionally has its own sizing idiosyncrasies.    Little Miss is our petite brand which also comes in little girls sizes age 6,8,10.   Little Miss is often shown as XXS, XS, S, M etc .   Miss and Trend usually are size 32-52 or UK 4- 24 but when an item goes across sizes T0, T1, T2, T3 etc is used.    For example T4 suits a 20 – 22.   IF YOU NEED ADVICE PLEASE ASK ONE OF OUR FAB TORTUE CONSULTANTS – THEY ONLY WANT TO HELP YOU x
