Guess has been accused of using his designs without his consent.
A graffiti artist posted a picture of a Regent Street store and suggested shoplifters visit.
He asked if it was wrong for people to do the same thing to their clothes.
Clothes bearing his images were in the shop. Guess didn't say anything.
There is a new collection with graffiti by Banksy.
The collection was created in partnership with Brandalised, which licenses designs by graffiti artists.
Guess closed the store to the public and put security in place after the artist posted his message. The staff in the shop didn't want to speak to the radio station.
The graffiti of Banksy has had a "phenotypic influence" on popular culture according to Guess chief creative officer PaulMarciano.
The new capsule collection is a way for fashion to show its appreciation.

According to Liz Ward, a third party, called Brandalised, claims to have the rights to commercialise and use the artwork.
She didn't know if Banksy approved or knew about the deal. Maybe his comments are there to create a guerilla marketing campaign if he knew about it. If he didn't know about it, he must be annoyed that mainstream companies and brands don't agree with his views.
The short point is that Brandalised and Guess should be taken to court if they are found to be in violation of the artist's work. That may be impossible since she wants to be anonymous.
She said that copyrighted works can cause long term commercial damage, but is usually a civil offense.
Brandalised has not commented.
The EU Intellectual Property Office allowed Banksy to keep his trademark on a picture of a monkey wearing a sandwich board.
He revealed on Thursday that he had traveled to Ukranian to create seven new pieces.
There was a woman in rollers and a gas mask holding a fire extinguisher in his artwork, as well as a child throwing a resemblance to Putin to the ground.
