It’s official. Rihanna will be on Vogue’s March Cover. While this is Rihanna’s third cover for the fashion magazine, the style icon shares some of her fashion obsessions.

According to E! Online, inside the march issue, the Grammy Award winner has specific rules that creates her eclectic style.

“If I'm wearing a top, I don't wear a bra,” Rihanna told Vogue. “If I'm wearing a bra, I just wear a bra."

Along with her under garments guidelines, the singer revealed that her real fashion inspiration is menswear.

"I love baggy things. I wear men's clothes, men's shoes, oxfords, creepers," she said. "When I was thirteen or fourteen, I didn't want to wear what my mom wanted me to wear. I was very much a boy in my style, my demeanor. All my friends were guys. I loved things that boys did. I loved being easy with my clothes. I loved wearing hats and scarves and snapbacks on my head. It was my way of rebelling. I wanted to dress like my brother. After a while, it was just easier for Mom to dress us both the same. We wore the same jeans, the same T-shirts."

Although Rihanna favors men inspired clothing, that doesn’t stop her from wearing high heals. Page Six reported that the pop singer also has particular guidelines when in comes to wearing her 4-inch, pointy heeled Saint-Lauren boots.

It’s not about pain,” Rihanna says. “It’s about the commitment. I say to myself, ‘I want to look like this,’ and worry about the pain later.”
