Unknown AP Cutsew bought second hand at a pop up store

Please Read my Terms of Sale, thank you.

I bought this cutsew at a pop-up lolita/j-fashion shop. I know i am the 2nd owner of this piece.
The cutsew comes with a cute detachable/neck piece, and is adorn with tiny star buttons. This top is very comfy and ha been dry cleaned. Please know it does have very minor makeup stains on the neckline, as well wrinkled on the arm cuffs, though im sure if you iron the wrinkles would come out.

As for size, i say it fits a US size XS to M. Material is a tad stretchy but a L would be pushing it.
