Of course it is alright. It makes a lot of sense to get to know your size and the styles available. Even if you are lone at the moment, there is no harm in doing so.
Thanks guys... yep, I do have a fella... just though it might be an idea to be prepared like a good boy scout! Don't wear rigs so no idea of style or size!
Oh dear no. I would just wait for your mister to arrange a special night out with all the romance pre-arranged, get down on one knee, propose and hand you a ring you don't like which is the wrong size.
i knew a girl who went and bought herself a ring to give to her boyf to give back to her...he hadn't even asked her and they hadn't even discussed getting engaged, and hadn't even been together that long and didn't live together, she just did it...they didn't last much longer...
