I always love to see what brides have chosen for their somethings (old, new, borrowed, blue). Some brides collect them throughout their engagement, other items are received from family members. I carried items my bridesmaids gave me the day of: a vintage button sewn into my cardigan, tiny blue flowers in my bouquet, a new anklet, and a borrowed cross necklace wrapped into the ribbon around my flowers.
These special little details add that extra touch of personalization to your day. If you need some inspiration, I've compiled some ideas for your "something blue":
Eyeliner can add a pop of color to your makeup in pictures and also be an easy something blue. I love the jewel toned blue in this picture. Via Pinterest

 Hairpins
Another something old and something blue combination: blue vintage rhinestone earrings
 
 
 
 
Many brides choose to add special little details to their wedding dress in blue embroidery, such as their new initials or pretty blue hearts. The bride below sewed layers of blue tulle into her dress that could only be seen when she lifted it to walk. So fun!
