ASOS Spike + Gem Cap, $43 (ASOS)
Take a hat of your choice, tons of gems, buttons, studs, and spikes...and go crazy! Using both hand stitching and fabric/strong craft glue will let you attach each embellishment according to type.
THEIR WAY:Shourouk Leitmotiv silver-plated Swarovski crystal necklace, $440 (Net-a-porter)
Paint a chunky crystal pendant with nail polish or acrylic paints. Attach a bead cap with head pins/jump rings to either side, and glue cord into the bead caps. I know Michael's sells Paracord that is essentially what was used in this necklace. Any kind of "sports" cord can work! At the ends, glue another set of bead caps and add a jewelry clasp.
THEIR WAY:Marc by Marc Jacobs Katie Neon Leather Clutch, $358 (TheOutnet)
A strand of flat curb chain sewn to the front flap of a clutch can recreate a similar look. Could be a useful way to use up that pesky leftover length of chain!
