She is undoubtedly one of Hollywood's most breath-taking celebrities.

And Rosie Huntington-Whiteley was a vision of beauty as she exited cosmetics store Violet Grey in West Hollywood on Tuesday.

The stunner, who owns her own make-up line, left with a bag full of goodies but struggled to maintain her modesty in a slinky top as she went braless.

Show off your shoulders with Rosie's top by The Reformation

We spotted Rosie running errands in LA wearing this sexy, silky, off the shoulder top by The Reformation.

This hot pink number is just the ticket to sartorial nirvana that we needed for our summer holiday under the sun.

The Reformation is quickly becoming one of our favorite labels, with Taylor Swift recently wearing 3 (!) different outfits from the eco- friendly label to Karlie Kloss and Malia Obama--it was only a matter of time before Rosie joined in on the fun.

The model, who constantly travels, is often seen rocking her favorite pair of cropped, black jeans.

Her jet-setting ventures could explain the reason behind her choice to recycle her clothing.

In an interview with Vogue UK, Rosie revealed her decision to pack less, thus resulting in a four-choice colour palette. 

'Recently, I've challenged myself,because I come back and forth from LA so frequently, to pack less.'

'The last few times I've thought, "Ok, this is crazy, I pack so much, I don't wear any of it, I need to get more organised." So I said to myself, "I'm only going to pack four colours: navy blue, white, grey and black."

'The same with shoes, the same with accessories, the same with all my clothes.' 

Rosie realized how simplifying her life truly made a difference.

'It was amazing because basically it meant that everything worked together,' she began. 

 'The white shirt worked with the black jeans; and then the black jeans worked with the grey sweater; and the grey sweater worked with the white pants, so everything was interchangeable and versatile.'

'Like taking a uniform as opposed to just lots of different things,' she concluded.
