I haven't been on here in ages but knew this was the place to find carrier experience

Which one?
My Lu is 3.5 lbs and 8" at the shoulder and 10" from her chest to her backside. I have been looking for a good discrete purse type carrier. I'm pretty sure Lu would be comfortable in either.
The Sadie is very much like the Jaraden Soho in appearance and size. Unfortunately I can't look at either carrier in person. I'm not terribly tall so I am concerned whether the Sadie might be a bit thick?
I have read lots on here of others experiences with the Petit and the Soho. Does anyone have experience with both and have a favorite between the two?
