The great cover-up! Make-up free Kate Upton conceals her famous curves after frolicking around in a tiny string bikini

Her enviable curves are what put her on the map.

But Kate Upton kept her assets under wraps as she headed out in New York City on Monday.
Opting for a casual look without losing her feminine flare, the 21-year-old model concealed her bikini body in a thin grey blouse and skinny pastel pink trousers.

She teamed the pieces with a pair of white flats featuring black bows on the toes, and toted an embossed blue Celine tote.
Going with her laid back vibe, Kate had her blonde locks swept into a loose 'do and covered her eyes with silver aviator sunglasses.
This was ensemble was much more conservative than what Kate wore on Sunday.

As she filmed an ocean-front scene in The Hamptons for her upcoming film The Other Woman, the supermodel showed off her famous curves in a particularly tiny two-piece.
The string bikini was nearly identical to the one she famously donned on the cover of last year's issue of the Sports Illustrated swimsuit issue -- making her a household name.
Directed by Nick Cassavetes, the comedy is due out on April 25 next year and tells the story of a woman who realises she is not her boyfriend's primary lover.
Cameron Diaz and Leslie Mann play the spurned duo who form an unlikely friendship as they team up to get revenge on the love rat who has been seeing a string of women as well as them.
Also making a splash is Nicki Minaj, who plays Cameron's opinionated assistant at her New York law firm.
