I wasn't, what i call a "phoebeliever" until I gave her a chance & tried her on at the store. The regular size didn't look right on me (big & baggy), but the small size looks better (i have small cranberry). I like the slouchy look, but the small still seems to maintain its shape, plus it stands up on its own.
The main reason i resisted for so long was the compartments, which I'm honestly still trying to get used to. I've only taken her out about 3 days, & I'm playing with how best to organize her. Not a big deal though. I did carry her around the house for a few days before snipping the tags, so I'd suggest the same for you. You honestly won't know until you try it out for yourself w/ your stuff in it and maybe even different outfits, especially a coat.
