Design duo The Blonds have teamed up with Gwen Stefani to create her This Is What The Truth Feels Like outfits and they sat down for a chat with Billboard about the exciting fashion collaboration. 

When asked what Stefani's specifications for her stage costumes were, The Blonds explained that stretch and flexibility were essential because she has lots of quick changes and there's lots of movement in her latest show:

"It entailed adding stretch to structured pieces, maintaining the embroidered look and placement without anything catching during choreography, along with durability and comfort mainly. Once that's all nailed down there is an entire team that will maintain these pieces throughout the tour. But quick changes can be very stressful so zippers, snaps and Velcro are a must!"

They also revealed that Stefani's 'Velvet Rose' corset is a favourite piece in the collection, adding:

"The Velvet Rose corset piece was a special request to allow for choreography and her trademark bralette silhouette. It was inspired by the red queen in Alice in Wonderland, a sort of "painting the roses red" moment except we crystalled them red with Preciosa. Gwen is one of the most inspiring and glamorous women in music and fashion. There is no one like her, she has her own sense of style and we really admire anyone that does what they feel is right for them."
