Oh, Brooklyn, it has your name all over it.
I wish I could help but I have not seen it. Maybe email customer service and see if you can get exact item measurements? Sometimes that is possible.
Hoping someone who has seen it jumps in. I don't know how SE clothing fits.
I do know that I bought a MEDIUM from Massimo Dutti vs. my usual Zara small (same parent company) and so, well, you never know. I could have worn the small but everyone agreed the medium looked a bit better on me.
