I see F.M. on a jacket label here: Code: https://gem.app/product/f-m-womens-jacket-grey-size-m-wool-collared The label on this jacket says "Made in Switzerland" but it also features the Italian flag.
There is no label on this dress that says "Made in Switzerland". Just the FM label. Also says to dry clean only. Oh, I see. I went to the link and saw the FM label and made in Switzerland. Do you know who it is?
