Skwosh's online business has recorded an average monthly revenue up 67% from last year.
In the lead up to Christmas, it recorded an additional 246% for sales in December compared to its monthly average.
Best sellers included the Sunny Boy shorts, selling 50% more than its second biggest seller Mr Pinchy and the Big Blue coming in at third.
Following the launch of its SS18/19 collection, the brand welcomed its first basic tee range and party shirts.
The Cactus party shirt and Berrylicious basic tee were the best sellers, selling 50% more than other styles.
The average basket size on its online store has increased to $150 per purchase which it has attributed to product line expansion.
Wholesale is also up 74% from last year.
Skwosh has continued to use social media to market its products.
On the back of Ed Sheeran posting on Instagram in the Cactus party shirt, sales skyrocketed across the EU and UK - particularly in Italy, Greece and Scotland.
The brand now ships to 45 countries - up from 26 countries this time last year.
