I'm pretty sure I've seen these before, but I just re-fell in love with Etsy seller Paraphernalia's whimsical necklaces after being reminded about them by the new blog Eclectic. Inspired by vintage illustrations, her necklaces are trompe l'oeil triumphs! Take a look:
Vetements skinny-tie necklace, $27. Sorry, I bought this. I'm picturing it with a V-neck dress and oxford heels (if I liked them).
Vetements polka-dot necklace, $30.
Vetements fur-trimmed coat necklace, $17.
Fauna fish necklace, $27.
Lots, lots more at Paraphernalia.
