Rihanna Sexy New Photo On Instagram, Featured In New Video Sporting Items From New River Island Clothing Line [Photo/Video]

Rihanna posted a sexy new photo on Instagram in which her side-boob is exposed, on Monday, in light of her new River Island clothing line that will be released later on this month.

This summer collection will be her second line of clothing by River Island, Gossip Center reports. "I needed to make clothes for fat days that I have. I made a piece for everybody in my crew, we all have different body types and different tastes," Rihanna said in a new video about the collection. "Some are braver than others, but, you know, I think like that because that's how all the women in the world are. We're all different; we all like different things, we all have different occasions, different moods, different body types."

In the video, Rihanna is filmed trying on some of her favorite pieces and speaking about some pieces as they are displayed on various models. Rihanna's co-designer, Adam Selman, asked her about her inspiration for the prints within the collection, according to MTV. "The floral, I think, is very timeless. Usually it's very chic, very chick, very flirty, and fun, and that's what I wanted. But I don't want it to be typical floral with bright colors, I wanted it to be gangster-a little more muted, so you can wear it with rock 'n roll stuff," RiRi responded.

She added, "I just wanted stuff that I want to wear, because at the end of the day, that's what got me into designing...I was being selfish. But hopefully, my fans and the River Island customers will have the same taste," according to Marie Claire.

This new River Island collection includes a number of 90's inspired pieces that offer an opportunity for warm weather fun this summer, according to MTV. Most of the pieces in the collection are tight fitting and allow for a certain degree of skin exposure.

The new collection will feature affordable fashion pieces such as sexy bodycon dresses, off-the-shoulder crop tops, denim jackets, mesh skirts, tons of tie-dyed pieces (perfect for hitting the beach in Jamaica, RiRi says) and T-shirts emblazoned with pictures of her face that were taken by Melissa Forde, Rihanna's photographer friend, Marie Claire reports. The clothing line is set to be available online and in stores starting on May 25.
