NWT Blouse from the brand Queerness.

I found a couple of small brown spots under the arm (pictured) but otherwise it is mint. I have only tried it on.

There is a drawstring at the upper arm to tighten the sleeve rather than elastic.
The sleeves are detachable with buttons.

Bust: 82cm (pictured)
Waist: 82-118cm

Please note I have a cat in my house. I try to keep her away from my clothes and will attempt to remove any hairs etc. before postage. However I cannot guarantee there will be no contamination.
