Set in the former historic tailors’ quarter in Paris’s 8th arrondissement, Guilson is a Gentlemen’s and Ladies’ bespoke tailor. Its clientele consists primarily of men and its products are positioned at the upper end of the market. The firm’s managing director makes frequent trips abroad to cater for the wardrobes of personalities.
