Yeah easily my most used is longchamp le pliage(the neo all black one), carts half my life around(laptop, gym gear, shopping etc).
My finger has hovered on the add to cart on Evelyn, i love the smell, look and saturated colours of the leather with the quality look of the bag. One thing holding me back is i wish it was zippered at top, i commute on public transport and i'm often running for trains etc, my house keys and card for train(yearly ticket is close to the price of a chanel classic flap) need to be in a secure compartment so i need a secure close on bag, zip top would be my preference.
Second most used bag that is more traditional handbag style is actually another longchamp bag, no idea what it is called, its a plain leather cross body handbag, simliar in size and features to LV pochette metis, in that it has a zippered compartment on back - fantastic secure quick access for train ticket and id for work, it also has a D-ring type attachment in main compartment with a leather strap where you attach your keys. I wish every handbag i desired had these features.
