The eyes on both of the dolls are pretty much the same. The eyelashes are different, though. Georgia has thinner, softer, and lighter eyelashes, where as Felicity has thicker, darker, stiffer eyelashes. I feel like the face molds haven't changed all that much, since all of my doll's faces seem to look slightly different, whether they are longer, chubbier, or thinner. The face paint is noticeably different. Georgia's looks more natural in my opinion. Her lips are a slightly lighter colour, Felicity's are peachier. Georgia's actual vinyl looks really natural in person, and Felicity's looks like someone who's wearing more blush, bronzer, concealer, makeup of any sort really. Georgia's cheeks look more naturally pink, while Felicity's look slightly more girly.
see this video), or if it's just that Pleasant Company's arms are bigger.
The only real difference I see in the legs, is the colour of the vinyl. If you ever get to hold a Pleasant Company doll in your hands, you'll notice that her limbs are slightly softer, or squishier. I'm not sure why. Georgia also has larger feet, so her feet are to big for the tighter AG shoes. If the shoes are tight on your newer dolls there's a very slim chance you'll be able to fit them on your Pleasant Company doll.

I really hope this has helped you in any way, if you have any questions about either doll, feel free to ask in the comments and I will be glad to answer! :)
