Well I've been mulling it over and I've decided to order the Mia Michele Sadie.
I was so excited to find a Jaraden Le Petit still in stock somewhere as I have wanted a Jaraden bag for ages. (I've been looking at them since the Getaway came out) . . . In looking at the features and sizes and reading a ton of reviews about the Le Petit and the Soho (the bag nearly identical to the Sadie) I think the Sadie will fit us best. I don't really think I could have gone wrong with either carrier but I like that the Sadie is black and maybe a bit more the style of a purse I would tend to carry. Hopefully the extra width will be nice for Lu and not too wide to be comfortable for me.
Fingers crossed the Sadie is as good of quality as I have heard the Jaraden carriers are. I've been told they are good quality so I'm trusting that to be true.
Next buy some faux mink to make a snuggly blanket

Lu is going to be sooo comfy and spoiled! I've had this idea in my head of the perfect spoiled puppy carrier. Now to see if I can actually make things look like I see it in my head
