This is an offrand blouse in a nice soft pink shade.
Arms are see through but the bodice isn't (except for the lace parts).

I bought it from Vinted, it must be around size 46-48 FR / 16-18 UK.
Perfect for plus size lolitas!

Measurements: 
Bust under the arms : 60cm flat
Shoulder to shoulder : 40cm flat
