All good points, thank you. I hadn't thought of the "professional" vs more "cute" vibe. For sure the 30 will house more essentials at the office. Thanks!I'm 5'2 and find the 30 to be a perfect size in proportion to my height. I found the look to be more sophisticated as opposed to the 25 which conveys a look which is cute. Since I use the bag when I am in a working girl mode or attending meetings with clients the 30 gave off a more sophisticated vibe and held my needed essentials. If you're wearing the bag for weekend shopping and lunch with the girls the 25 is perfect. Choose the size that matches your life style. GL. Can't wait to see which one you choose.
