I am a huge fan of fashion accessories which encompass my initials. This particular "A" is from a wine charm. But, rest assured, my current key chain is an "A". Also, back in the day, I rocked an "A" necklace made of rhinestone. I cried when it finally broke into a million pieces after years of use.
I love this look because it is retro and yet modern at the same time. It gives an ordinary business outfit a little flair without going over the top.
