Leather, Lace and Velvet
All of these wonderful fabrics make a perfect match, you get the soft and delicate with the rough, and the shiny with the matte.
If you want to take it a step more trendy at this point, you can add white pearl details in the accessories.
The wool fabric is also a trendy piece right now and matched with the beautiful black lace, once again you balance the rougher wool with the more soft and delicate lace.
I love these contrasts and the fact that they work so well together. And remember you can always tone bring it up a notch or town it down to work for you.
