She's spent the last few months decked out in designer looks by Armani, Stella McCartney and Emilio Pucci while promoting her big screen debut in the upcoming flick Battleship, but Rihanna's closet contains at least one affordable label.

The fashion-forward singer recently stepped out in two dresses from the British clothing chain Topshop (Kate and Pippa Middleton, Olivia Palermo and Taylor Swift are all big fans).

For dinner in New York City on Monday she showed off her curves in the line's slinky silver maxi, which is on sale right now for just $35 (from $76). She paired it with a white and gray denim hoodie, Manolo Blahnik sandals and a luxe Celine bag.

A few days earlier she was spotted out in an ivory button-front sleeveless dress ($76), which she wore with Pretty Polly black tights and Christian Louboutin pumps for a night out in Santa Monica, Calif.
