Thank you for chiming in ❤️Hope you don't mind i chime in.
BML runs a little bigger and if my observation is correct, the shape is different from Love (when i tried at the store, i wore the BML alone, not pairing with Love).
I am size 15 Love, and tried on 150 (smallest) for BML. It definitely feels looser than Love.
So i reckon has to size down for BML.
