RIH-TROSPECTIVE: Opening Ceremony is paying a special tribute to Rihanna in March. The New York-based specialty retailer, which will stock the singer-cum-designer’s debut collection for River Island beginning Tuesday, has curated an exhibition of seven of her best-known outfits to fete the in-store launch, called “RIHtrospective.”

The number of looks to be exhibited bears a certain significance: Rihanna has released seven albums in seven years, received seven Grammys and seven Billboard awards, graced the cover of Complex seven times — and then there was the infamous, globe-trotting 777 tour she went on to promote her album, “Unapologetic.” The outfits span from her stage to red-carpet looks and testify the chameleonlike qualities of her wardrobe, whether “really pulled together or grungy for performances,” said her stylist, Mel Ottenberg. Rihanna helped hand-pick the looks, which include custom pieces like the Adam Selman-designed pink lace minidress that she wore for the Victoria’s Secret fashion show last November.

The Rihanna for River Island collection, which ranges between $45 and $350, will only be available at River Island and Opening Ceremony locations, as well as online at openingceremony.us. The exhibition will be presented at Opening Ceremony’s New York flagship at 35 Howard Street, where it will remain for three weeks.
