Wore my JJ blouse all day yesterday. Poopily, the crinkle in the crinkle cotton relaxed as it was worn (especially across the back) so by the end of the day the back was VERY saggy and loose. The front was still fine (and still gaping slightly :P). Not sure if I’ll try and take the back in more or just chalk it up to a learning experience… maybe I’ll see what it does after the fabric’s washed.
