Since I just purchased my first b-bag earlier this month, I wrestled with this question for a while! I chose the style THEN I chose the color. For me at least, it was important to do it this way, because I think certain colors look better in certain styles. I ended up choosing a city in mogano. Mostly because I LOVED the depth of color in mogano, and I knew that I wanted a brown bag in that style. If I went with a first, I would have gone for black or plomb. For a twiggy, I would have gone with a fun blue. A lot of it just has to do with personal style, wardrobe, and lifestyle, KWIM?
