I have the larger size Juicy carrier (not the one shaped more like a bowler). It fits my 8 lb girl, but I doubt it would fit any bigger. I'm trying to find a picture...
Found it:
NWT Juicy Couture Pet Carrier Pink/Brown 100% Authentic - eBay (item 250409596324 end time Apr-28-09 14:13:57 PDT)
Mine is navy with red accents, so my boyfriend wouldn't be embarrassed to carry it.
I got it at Nordstrom last year.
