The Purse Wedgie

I got this article from Glamour about the "Purse Wedgie"...Huh? Yes, my reaction exactly. Apparently the purse wedgie occurs when your shoulder purse decides you need to show a bit more skin, in this case, a bit more booty. So it rides up your skirt until your badonkadonk is out for all to see.

I'm not much for skirt wearing (surprising right?) however my equivalent to the purse wedgie is when my shoulder bag wants to pimp me out and turns all my t-shirts into belly shirts. Does anyone else have this problem? I'd be walking down the street and next thing you know, my belly is out because my shoulder bag causes the side of my shirt to ride up. 

I have yet to figure out a solution to this problem because:

1. I don't like to tuck in my shirt. 80% of the time, a tucked shirt is not attractive. 
2. I can wear the shoulder bag on one shoulder (not across the chest) but that defeats the purpose of the bag. Its not comfortable. 
3. Backpacks make me look 10 years younger. 

So who has THE solution. I'm all ears.
