Hi! I am looking for my very first BBag!!! Im sooo excited but I want to make sure I get the perfect size for me. I used to think I wanted a first, but looking through the pics they seem a little on the small size but I like their shape. Then I thought I wanted a city but they look too large. Do you think a twiggy is in between the city and first size. I love the slouchy look and I know the city does that but I have not seen any pics of the first doing that. Does a twiggy slouch? Ugh! I am just so overwhelmed by all of this and i really want to make sure that I get the perfect one since it is such a huge purchase for me!
