Which fashion brand has a tree logo?

Mulberry is probably the answer you're looking for. The Mulberry tree features on the brand's logo, and it is also where the company gets its name from.

But there are other fashion brands with tree-based logos:

Timbaland is one company that has a tree logo on all their products.

And skate brand Element also have a "tree-like" logo that could be what you're talking about too...

There are probably other brands with trees on their logos that I'm missing out here, so if the one you're looking for isn't listed, please comment below with some more details!
