we have the same ring size. Last time i buy a ring for her i just measure it on my finger and it fit one her. so i measure the circumferenze of my finger. I tried many time, a bit worried when i see that (R 1/2) was the max size that i can choose from the list.
I have asked now her roomates to find a way to measure one of her ring to be sure
Hope none tells away your plans girls are talking...
also measures are different from finger to finger, which finger did she try that ring on? still, modifying the ring by enlarging or removing few measures is not that hard. i think any jewelry shop around your place can do it, its the least thing to worry about
my girlfriends sleeps deep, it takes a tank to wake her up...i bought some plastic dummy rings with different sizes and while she was asleep at about 2 am (ive had an alarm set, even the clock ringing didnt wake her up) i've tried those dummy rings on her.
