This bag is the perfect size.  I love the lining and inside pockets (3 - 2 opened slit pockets / 1 zipped pocket) and the fact that it does zip vs. snap to close.  The best kept secret in this Vera Bradley are the two, front slant pockets that provide the perfect catch all for a cell phone and/or your keys so you don't have to look for them in the compartment area!!!!  They are really a nifty and handy extra!!!  The shoulder straps are comfy and actually stay on my shoulders....and yes, this purse can fit securely under your arm...plenty of strap room to allow that comfort!!!  You could fit a small tablet inside the purse and a nice size wallet with still enough room for other items.  Perfect in-between size....not too large, yet not tiny either!!  I love it!
