Retiro is a handheld and shoulderbag, she is a little smaller in size but the strap is a little wider, Estrela is a handheld and crossbodybag, she is bigger but the crossbodystrap is slim.
Retiro can be but on the flor, as she has protection footnails (dont no the word) ... Estrela has no protection.
In my eye Retiro is more of a handbag and Estrela is closer to a shopper.
Both are very beautiful! I personally would prefer the Retiro but would buy a crossbodystrap for her, too.
