Coolabi is continuing to build the programme for Scarlett & Crimson, with Poetic Gem signing up for apparel and Myridium for perfume.
Both product lines are due to launch this autumn and are aimed at the core target of teen and tween girls.
Poetic Gem will create a range of leisurewear, while Myridium will be producing Scarlett & Crimson perfume and coffret sets. These will be an extension of the successful cosmetics and accessories range created for Boots and Superdrug by Ruby Hammer and Millie Kendall.
"We are very pleased to be working with both Poetic Gem and Myridium," said Anna Hewitt, head of licensing at Coolabi. "It is an exciting time for the Scarlett & Crimson brand and we look forward to introducing apparel and perfume to the market later this year."
Elliott Matthews, director at Poetic Gem, added: "Scarlett & Crimson's resonance among teen and tween girls, along with its originality and sense of style, make it ideal for the apparel sector. We are delighted to be pioneering Scarlett & Crimson's entry into the leisurewear market."
Colin Barthelmy, MD of Myridium, continued: "We are setting the scene for a great collection story of fragrances appealing to the ever changing trends and personalities of today's teenage girls."
