London, Aug 13 (IANS): Pop star Rihanna has unveiled her second autumn-winter 2013 collection for high street British brand, River Island.

The singer has designed the collection in collaboration with designer Adam Selam. She will release one lot in September and the next in November.

The collection includes wide range of apparels and accessories like floor-length mesh dresses, army camouflage-patterned crop tops and daring bodycon dresses, reports femalefirst.co.uk.

"I literally designed everything I wanted to wear, exactly how I wanted to wear it," femalefirst.co.uk quoted Rihanna as saying.

Selman said: "The way I approach winter style is to layer up summer clothes and Rihanna does the same. But there are coats and sweatshirts - those pieces were key. It's a little more refined."

The new range also features several underwear garments which are emblazoned with Rihanna's nickname, Riri, on the rim, "G4LIFE", a phrase taken from her 2009 song "G4L" which stands for "gangster for life".
