i love both too! i have the abbey in brown trim and it's a very versatile bag, i think the abbey is more classic/plain and the wave is a lil more on the trendy side that you can dress up or down for work or on the weekends. i pre-saled both the white leather wave at saks and the beige canvas with brown trim online; can't decide which to keep! hope 15 days will be enough for me to make up my mind!!
haha-me too. i got both the brown and white trim wave ...glad i'm not the only one let me know which one you end up with!
