100% Right handed, but carry it ALWAYS on my left shoulder... I also HAVE to hold a phone up to my left ear, with left hand! Now that I think about it, I probably do this because sometimes you have to hold the straps in place or prop them back up on your shoulder if one slips off, so I do this with my left hand and that way I will always have my right hand free to do other things.
I'm right handed, and wear my bag on my right shoulder. I wish I could alternate which side I keep it on, but it feels so weird to have a bag on my left shoulder!
I am right handed and just about always carry my purses and bags on my left shoulder, arm, hand. I am trying to figure out why and I think it has to do with my kids being younger I would typically hold their hand in my right hand so I didn't want a bag between us. That is the only thing I can think of. Prior to kids I have no clue what I did.
I carry my bags on my left shoulder but when they're in my hand it's my right hand (and I'm right handed). It's funny, if I put my bag on my right shoulder it falls right off I just can't carry it on that one lol
I am TRYING to re-teach myself to carry shoulder bags on my left shoulder. It's not easy because I've carried them on my right my whole life. I've mostly switched to arm carry, which is always my right arm. I am right handed.
