After all it is a wedding tradition and it could be one of your “somethings.”
A garter was worn to keep pantyhose on but since it no longer acts as a functional item it’s up to the bride to decide if she wants to wear one.
You may receive one as a shower or bachelorette gift, a relative may pass their’s down and a friend may lend you hers but whether you decide to take part in this tradition is up to you.
I don’t know many brides planning on including the garter toss in their wedding reception, but if you are you may want to get a themed garter and wear a gifted or prettier one for the wedding, which you can keep as a memento.
If you decide that you do want to wear a garter I recommend The Garter Girl. Julianne Smith hand-makes custom garters in a variety of fabrics and colors and can also add a monogram, your wedding date, names or a phrase to your garter.
