Since the Mandeville was done (much better than I would've, my purse is a mess inside!), I'll do one of my Silver Montego. It probably doesn't need a guts post because it's big, but I thought it'd be fun anyway.
Don't mind the pink on the hardware, it's a reflection from my red LAMB gothic hoodie. Inside there's a zip pocket, two phone-shaped pouch pockets, and a flap panel pocket you can put stuff in and behind.
My stuff inside (I know there's a TON of room left, such a joke, but I just like having the *ability* to carry more if need be. LOL. I'd have my keys in the pic, it's a huge-ass keychain, but it's hanging by the door so it's impossible for me to leave without em):
The stuff that was in it:
phone, pen, wallet, mirror, various cosmetics, 3-hour mints (should be called 3-minute mints, honestly), L lotion, L compact, hand sanitizer, gum, lipstick saddle key pouch, sunglass case.
And just for lambs and giggles, I took a pic with a standard-sized notebook in it (11x8 thereabouts) for the lambies at work. It fits just under the zipper, and doesn't get in the way of zipping, as long as there's nothing underneath it. (You can see the corner of my rasta mandeville at the bottom of the pic, hehe)
And I love this side panel so none of your stuff falls out! Before getting this bag I thought only the Love collection bowlers had this panel.
