I mean... there is just so much that you can do with a bikini and I feel we've seen almost all variations yet (except for just throwing new patterns on old models, but that seems kinda boring to me)...
I for one am happy that this isnt just bikini #50 but instead something I might actually glamour - personally I dont think my Roe looks that great in bikinis so I'm happy to get something that looks nice on her instead of adding yet another boring bikini to my collection.
My guess would be that this isnt about "ethics" (such a grand word to use in regards to some pixels...) but more about trying new designs that are actually different from a 08/15-bikini that you can only take so far.
