Kate Upton thinks Guess' problems run deeper than Paul Marciano.

The 25-year-old model-and-actress has accused the fashion brand's co-founder of sexual misconduct and though she is amazed that he's kept his position for so long, she suggested the company needs to overhaul a lot of their processes.

Asked if she's shocked he hasn't resigned or been fired, she said: ''Tell me about it. I think change comes from the top, but he's been there for years so it's more than just firing him to change the culture inside the offices.''

Kate admitted she would consider working for Guess again, but thinks they need to alter the whole ''culture'' of the company before she'd listen to any offers.

She told TMZ: ''I think it's important that Guess changes the culture of their offices, and there would be a lot of changes that need to be made before I would ever consider working with them again.''

The 'Other Woman' actress was also asked if she had any advice for other women working for Guess.

She replied: ''Good luck.''

Kate first accused the designer of sexual misconduct on Twitter last week, and she has now spoken out about her alleged ordeal at his hands.

She told Time magazine that, when she first met him in 2011, he ''forcibly'' grabbed her breasts.

She added: ''He started feeling them - playing with them actually. After I pushed him away, he said, 'I'm making sure they're real.' ''

As the meeting went on, she claimed he continued to touch her in a ''very dominating and aggressive way''.

She added: ''At one point he forcibly grabbed the back of my head so that I could not move and started kissing my face and my neck.

''I remember not wanting to say, 'Get off of me' because I didn't want to open my mouth to say anything because I didn't want him to be able to put his tongue in my mouth. I had two options: do everything I could to wiggle away and avoid his pursuit, or punch the CEO of Guess. So I decided to just wiggle away.''

Marciano has denied Kate's allegations.

He said: ''I fully support the #metoo movement. At the same time, I will not allow others to defame me and tarnish my reputation. I have pledged to Guess and its Board of Directors my full support and cooperation with a fair and impartial investigation.''
