There are other artists who used the retro theme like Lee Hyori's U-Go-Girl
Using a Retro theme shouldn't make them copycats, any theme should be available to any group or artist. If another girl group used the retro theme would you call them copycats as well?I think not.
Ga-in’s solo album was also produced with a retro theme in mind as well.
Both may be using the same theme but both have different feels and styles
They both did very well their own way :)
Wonder Generation ♥
Here's B2ST's comeback using a theme similar to SNSD's Genie. would you call them copycats too?

Conclusion: Having similar/same concept doesn't always mean being a copycat,hey you haters!"
