This shirt by Marni is made of polyester, which is kind of weird, especially since it costs $610. But maybe that's because of the zipper instead of a traditional placket. Who knows? They may have used a really rare zipper or something. Can you imagine if this shirt had two-way zippers? Shit would probably cost, like, $1200 dollars! I actually didn't even notice the price until I looked at the shirt a second time, and, yeah, it may be a deal breaker. I don't know though because I'm not privy to your current financial situation. I just paid taxes and if there's one thing that makes being a freelancer even more of a strug profession, it's paying the fucking government. I CAN'T AFFORD $600 POLYESTER SHIRTS WITH ZIPPER PLACKETS. OBAMA GOTTA SPEAK ON THAT.
