Despite obvious pressure to design the perfect engagement ring, he said he simply followed his own advice... and it paid off. (She said yes!) Here he shares his tips on getting the ring size, choosing a style she'll love and avoiding the biggest ring-shopping mistake. —Anna Pezik
What are some ways a guy can get his girlfriend's ring size—without asking?
When she's not looking, borrow a ring from her jewelry box. Select a ring you know she wears on her ring finger and then take it to a local jeweler to have them measure it. If you think she might notice that it's missing, place the ring as far down on your finger as it fits comfortably, then mark your finger with a pen. You can also trace the inside of the ring on a piece of paper or make an impression of it in a bar of soap. The trick is to get as close as possible to her size, you just don't want to guess. I also suggest asking her best friend—girls discuss these things. Just make sure you talk to a friend you trust to keep a secret. And finally, you can also take her shopping to look at rings, it's not uncommon. Have a sales associate take her finger size for future knowledge...
