I voted return, only because you're already questioning it. Usually, if I don't love it immediately, I regret the purchase.....
I think you're right. It's the shiny leather that is too much and it makes the bag look like plastic and it seems almost fake. I like the silver and lilac though, good ting Zalando has free returns!I get the feeling that you're second guessing your choice & that you're not loving it. That being said, I vote to return it. Something is obviously bothering you with the bag & I feel like it will always bother you. If you're not satisfied with it now, you won't be satisfied with it later.
Return it and get the matte one [emoji171]
