It might be slow. It might plod along. But few things in fashion have remained such a classic. I would bet that 1) you already own several pieces of it and 2) you have probably had it many years. Trends come and go quickly, but this one seems to keep calm and carry on.
Ralph, Michael, Marc and Tory like it. I like it and have been wearing it since I was little. Do you have any guesses what I’m talking about?

Hawksbill turtle
Thank you Mr. Hawksbill Turtle for inspiring great fashion accessories and p.s. love your shell.
Before you report me to PETA, actual tortoise shell from a real tortoise has been outlawed since the 1970s. The tortoise we wear now is plastic. You can still buy antique tortoise shell, which is sold mainly in the form of hair combs and flatware/serving pieces. Before it was outlawed, real tortoise shell was used in everything from sunglasses to guitar picks. It definitely has a timeless quality to it.
Allow me to introduce you to my friend, Mr. Tortoise Shell (fake of course). He looks good just about anywhere, anytime, on you, around you, and near you.
