is it you in your avator and the photos in the blog that you put down in your signature? if so, i honestly think Cupid will look great on you! Navy would be perfect for your working style
i used to like MAM but once i got my Cupid i knew immediately it'd be the one i'd be wearing more. i don't bring a lot of stuff so MAM seems too big for me. now i usually wear my Cambridge satchel, RM mini Luscious Hobo and regular size MAC
like you, i am not located in US or Canada. i got all my RM bags online. i don't need to pay customs tax but just the shipping is killing

so, i really like those stores who offer free intl shipping

i am not advertising but i had great experience with
Amazon,
ShopBop and RevolveClothing.
Nordstrom and BlueFly overcharge on shipping so i don't recommend.
