Dianagrace.....Here's a few pics of my 31cm Box Bolide so you can see what can fit. First pic is without anything in it, next is a pic of the stuff I would probably carry if I took a magazine and pashmina along and the last is the bag stuffed. Even though I have the shawl partly out of the bag, it could easily fit completely inside with room for either a sunglass case or bottle of water. I might suggest the next size up from the 31cm though because even tho all of this fits nicely, you might want a tad bit more room to toss stuff in. OR perhaps the 31cm in either a Togo or other soft/slouchy leather. This way it "gives" more and you get more room. I love my Bolide and will buy another when the time is right. I think a Bolide in a soft leather would totally fit the bill but perhaps the 37cm is a little on the large and heavy side.
