In The Bustle Booth With Gavin Rossdale

When celebrities come to Bustle HQ, whether it's for a photoshoot, video shoot, or just to say "hi!," we want to give them the chance to leave their mark. Literally. So we hand them a pen, a piece of paper, a few questions, and ask them to get creative. The rest is up to them. This time, artist Gavin Rossdale is leaving his mark in the Bustle Booth.

Gavin Rossdale is best known for his music — both his solo career and as frontman of the band Bush. (Let's all agree that his 2008 hit "Love Remains the Same" just never. gets. old.) Now, the 52-year-old, who's still performing, takes on a new venture by expressing himself through another creative outlet: fashion designing. "It's a way different beast," Rossdale admits. "You realize that in life, you can be creative in so many different ways." Rossdale explains why he created his new line Sea of Sound, and how his girlfriend Sophia Thomalla unintentionally inspired the unisex collection.

Rossdale says his line puts "form and function" first: While it's fashionable, it's not uncomfortable. The pieces are inspired by what he wears in daily life, and things his girlfriend likes to wear as well (because there's nothing quite like an oversized, worn-in tee). "It's so sexy when my girlfriend wants to wear my shirt or something of mine," he says. "I love nothing more than when you see someone you're with — when my girlfriend wears one of my t-shirts. She wears it slouchy and beaten up and there's something nice about it." Sea of Sound pieces include slouchy button-ups, hoodies, t-shirts, and pants with the same look and feel he refers to.

Beyond his personal inspiration, Rossdale sees why the line is so meaningful in the big picture. "I like the idea that in such a questionable time in terms of the sexes, I think it's really fun," he says. "I mean, I make music for both sexes, why shouldn't I make clothes for both sexes, or all sexes? For everyone."

He carries this mindset into the creation of every detail in every piece. One of his favorites is a unisex, sleeveless shirt. "If I'm going to the beach and have a sleeveless top like I've got a t-shirt on... there's a little pop of red, that, on a guy looks cool with swim shorts and if you're a girl, it's really nice, you see the bikini through it," Rossdale explains. "I'm all about tiny details."

While balancing dad life, his line, and his music, the performer is keeping an open mind about what the future holds. "I find it really enjoyable, the process, to have an idea, realize it, whether you've been heavily inspired by something or whether you totally see it freshly," he says. "It's just really fun to do that."

Even though the artist is new at the fashion designing game, he's already thinking about how he can expand the line with specific pieces in mind. "I love dresses. All my life, I've been crazy about seeing nice, beautiful dresses on women," he says. "...they give such confidence to people."

While he'll continue getting input from his girlfriend Thomalla, there's one clothing item that is absolutely off limits to her. "One time I was messing around and was like, I want to make a beautiful poncho. My girlfriend was like, 'No f*cking way.' She shut that down," he says, laughing. But like his music, Rossdale will move forward with a mission to make people feel good. "My clothes are how I like to live my life: maximum comfort in an uncomfortable world."
