The singer made a special in-store appearance at London's Oxford Street, where she showed her pride for her debut line by tweeting,"In London launching my #RihannaForRiverIsland collection tonight at Oxford Street! #phuckyoclothingline."

She paired her staid-meets-sexy frock with Manolo Blahnik sandals, but took the time to show off her seriously fierce River Island beige-and-black high heel booties by posing with the stylish shoes.
