This is a Metamorphose Temps de Fille long sleeve blouse. It is 100% cotton has a cute flower trim lace on the sleeves and collar. Another cute detail is that its buttons have 'Metamorphose Temps de Fille' engraved on them. Judging from the buttons I would date this around 2010s but I cannot confirm as I could not find this specific blouse on Lolibrary. I wish that this blouse worked for me but it unfortunately doesn't fit me. My measurements are amateurish and done when laid flat.

Bust: ~41.5 cm flat

Waist: ~39 cm flat

Note that there is no shirring and is missing its waist ties. There is a slight yellowing on the collar as seen in the pictures but I don't think it's that noticeable when worn. The second button is slightly loose. This does come from a one cat home but I will try to remove lint as much as I can. I have gotten this 2nd hand and have only tried it on once. Please message me if you have further questions or want additional photos. I do not accept returns unless I had misrepresented something about the clothing.
