DOLCE & GABBANA
The iconic Italian fashion house will be providing the formal club suits and create the Dolce&Gabbana Lounge in the West Stand, as well as the club's main reception.
'We are really happy about this partnership and to be able to link our name to such a prestigious club like Chelsea,' said Domenico Dolce and Stefano Gabbana.
'We are big football fans, for us it means healthy competition, intense passion and great discipline.
'Football players are style icons both on and off the pitch and, on top of this, there is our love of England and of London, which have always been a source of inspiration for our work.'
Chelsea chief executive Ron Gourlay added: 'We are delighted Dolce&Gabbana will be our official supplier of formal wear for the next three years.
'Their designs for this season's team wear are exceptional and we're excited to be partnering with such a world-renowned and innovative design house.
'In addition to dressing the team, Dolce&Gabbana's comprehensive redesign of the club's Directors' Lounge and other key areas of the stadium will also serve to showcase our relationship over the next few seasons.'
