I gave a hint a few weeks ago in this post.
I was fully aware that I just acquired my first satchel from Cambridge Satchel Company (purple 13 inch) approximately 2 months ago (check here for the reveal post). And I had the feeling that the purple one would not be the last one lol. I then kept thinking on what colour for the second satchel would be. Well, I finally settled in classic green size 11inch (although classic orange was also on my list). Luckily there was a promo at Shopbop that I immediately grabbed the green bag without prolonged consideration *big grin*
Oneday I will make a post on the bag comparison between size 13inch and 11 inch :)
