Angela Ahrendts, chief executive at Burberry, has credited the performance to an increasingly strong brand and an investment in marketing.
She said: "In the all-important festive period, we are pleased with our 12% comparable sales growth.
"This performance reflects continuing strong brand momentum and our team's intense focus on retail execution, supported by a planned increase in investment in marketing, customer service offline and online and our retail portfolio."
The increased investment in marketing has resulted in the brand increasingly turning to outdoor advertising as it withdraws media spend from print.
Burberry also continued its strategy of focusing on social media over the festive period, with its Christmas activity including a "full festive takeover" of social media sites, including Twitter, Instagram and Chinese sites Sina Weibo and Youku.
Burberry also celebrated "25 days of Christmas" by publishing images and videos on Instagram each day.
Activity was supported by a film that showed London smothered in snow, set to Tom Odell's 'Hold Me' track.
Burberry also said a "halo effect" of the TV ad campaign that launched the Brit Rhythm for Men's aftershave helped the Burberry Brit clothing range "increase penetration".
