Oh wow, I just looked at the dress on the Anthro site and it turns out it is the same cut (just without sleeves) as this dress I got last year — I didn’t realize it was TR (for some reason I thought it was Maeve). This fits me well even in the chest. So definitely worth trying. In fact, I’m thinking of trying one of the sleeveless ones myself since it’s so hard for me to find good casual summer dresses!
ETA: my torso is definitely on the shorter side relative to my height. If you have a longer torso and need a small size, this may not work for you. I’m not exactly skinny (understatement of the year) and at 5’7” and 150+ I bought a size small. Of course, this is a whole new cut so sizing may be different, so worth trying!
