I would call what the girl is wearing smock. Chris is right that the second object is a wax seal stamp, but it would usually just be called a "seal", which is a bit confusing because a piece of wax imprinted by the seal, and used to close (seal) a letter is also called a "seal".

I would say 'a traditional blouse'. (or some people might say 'shirt')

US English - She's wearing a "peasant blouse." And that's a seal or a stamp for sealing wax.

I think the second image is a "wax seal stamp" - like this https://dribbble.com/shots/2034028-Wax-Seal-Stamp-Mock-up
