Taking the top spot this quarter is Gucci, up from second place in Q1.
Gucci's parent company Kering SA reported a 48.7% jump in same-store sales during the first quarter of 2018.
The luxury brand has exploded in popularity in recent months, especially amongst millennial and teen shoppers.
Gucci is benefiting from a resurgence in '90s style and capitalised with an ad campaign featuring Harry Styles.
