I’m 163cm (5’4) and I usually get 38 (US 6) on the bottom and 36 (US 4) on the top.
I got the M for the Mattia. Mattia is softer than I expected (which is positive). I think this goes well with many of my shirts, did not yet try with knits. I also got the Naella and like the Naella, perfect fit, comfy and soft and feels good quality / shape.

Rym Shirt in Ecru – got the 36 (US 4) which is my usual size. Lovely!! Soft fabric and color, perfect fit.Sezane,M,$160,5’3-5’4 5’3-5’4,Blouse,Bottoms,French Brands,Size 4,Size M,Skirt,Tops All Reviews,Sezane,Skirt,Top
