I recently found some items that have interesting details that you can easily copy, or being inspired from (which sounds better), buying affordable items. Because, of course, style is in the details.
A heart-shaped carabiner will add a cute touch to a coat (or a bag, a pair of pants and everything that has a loop). Be inspired by this coat by Love Moschino.
If you like denim and embellishments, look for a metallic ribbon and colorful rhinestones and get inspiration from these Liu Jo jeans. You can also embellish the belt loops.
Upgrade a dainty necklace with a velvet ribbon taking inspiration from this Miu Miu necklace. You only need a velvet ribbon and a small metal ring that you will find in a sewing shop for a few cents.
