Runway piece by SLP. This green colorway is really rare compared to the black ones which are way easier to find. Size is TTS but could also fit a slim medium. For the measurements, keep in mind the dropped shoulder (part of the style). Note that the photos make it look a bit aqua colour but check the last photo for a better colour swatch since it is actually more forest green.
