I rotate my bag and depends on the weather I live here in pacific north west so it's kinda rainy most of the time,but my most use are
LV Speedy 30 Demier ebene Coach ash gth sat satchel in black
My favorite bag for every day is an Ignes Mini Ormala. I don't own one any more, but I'm hoping to again one day. It's the perfect size, comfortable, light, and classic.
"MARC BY MARC JACOBS 'Classic Q - Natasha" is my favorite everyday bag. SO comfortable with squishy soft leather and it feels wonderful when it hugs against my leg. Love this bag!!
the bag i wear the most is my mulberry bayswater since i use it as a school bag, so obviously it gets the most use. if i'm going shopping & need my hands free i always wear my rebecca minkoff mini mac
