I have the Kwigy Bo Alyson carrier and I love it! It was worth every penny, in my opinion. It looks like a large purse, so no one ever knows there's a dog inside. Wenny weighs around 4lbs and fits in it with room to spare.
If you do a search for Kwigy Bo on YT you'll find some good info (and probably some photos)
That's what I did when I was researching!
Hope that's helpful.
