oooh go for the abbey! i have had it for a month now and ADROE this bag so much so i havent used my very much loved speedy for 4 weeks! the bottoms doesnt sag at all i find, it only keeps its shape and again keeps its shape alot more that it thought. Its a lovely bag to wear and feels good either full or empty, its such a good bag i cant rave enough. Oh its got shoulder straps but theyre not too long to wear on the crook of your arm sometimes either
