This has mostly been due to this recent TV show I watched, where this character in it pairs all her very chic work outfits with these very elegant and sleek looking necklaces, which I later found was sponsored by Swarovski. Intrigued, I looked up more of these necklaces and realized that while they are not super loud and ultra trendy, they are the perfect accessory for a smart work outfit. They are subtle and elegant, but are still very pretty and feminine- perfect for work.
Trendy elements are also subtly added to their designs, such as above.
This chained necklace is one of my favourites (left). The design is simple and elegant but still makes a statement. And this gorgeous purple crystal necklace (right) is just the thing to brighten up the usual dreary colors of work clothes in a quiet way. I can just imagine it looking fabulous, with a plain black suit and white shirt paired with simple diamond (or crystal!) earrings and subtle purple eye shadow!
