Love Etre Ceceile's irreverent tees and this one is no exception: Je parle Martien. Could only find an image of the white version... included to show fit. The tee for sale is black as per the rest of the photos.
It's a large. An oversized fit for a UK8 and UK10, loose on a UK12 and more fitted for UK14s and UK16s.
In excellent, barely worn condition.
