I know Forever 21 and Heritage 81, who I believe are under the same ownership, have had issues with stealing designs from other artists before. These rips, however, are more direct and are all from Local Celebrity.
Originals from LC are on the left, rips are on the right.
Pretty blatant, and there are a lot more on F21′s site now that are not exact rip offs, but similar in design and the slogan used. I’m trying to contact Local Celebrity about it now.
