You can get the B17 narrow, which is as the name suggests. Might be worth a try. No experience with the San Marco I'm afraid. If you were to get either though and find that it didn't suit you could just stick it on ebay and get a pretty good price for it so I wouldn't worry too much. That is of course unless your girlfriend will make you keep it, in which case you'll just have to grimace and bear it.
