Need Her Ring Size?
If you can’t take her to the store or ask her for her ring size. If sending out a true ring sizer won’t work. I have another option for you. On my business cards, I’ve attached a little, fake, adjustable ring. I can send one out to your requested address.
Once it arrives, you can say, look what I received today.. haha! You know she will try it on. You can tell her to adjust it or adjust it for her. Afterwards, sneak off with the ring and have it sized or send it in to your desired dealer to get an idea of the size she will need.
It may not be perfect but at least it’s closer than just simply guessing! Hoping this idea will help make the process smooth and maybe keep the element of surprise.
