Haha I had never heard of the term 'gallerina' before this post, but what a fitting term for a cliché I'm sure most of us are familiar with (no matter where we are in the world)
That said, I don't think you look cliche here @Lisa - I agree the long necklace look can sometimes look a bit overdone, but I think the harmony in this look (provided by the way your hair is bookended by both the necklace & lighter shoes) makes it seem more intentional without feeling too 'try hard', if that makes sense? Some of your reservations may come from the fact that head-to-toe black makes such a strong visual impact that we tend to associate the results of said impact with very particular things (like the clichés). Ha - & people look at me like I've got two heads when I say black is a difficult colour to wear which requires thought
