I don't have it, sorry. But I had thought about purchasing it several times and decided against it for the same fears you'r having. I think I'd be coming out the top!
Just like you, I loved it on the site, it looks so cute. So not cute in real life. Low cut and its shorter in the torso than it looks on the site. ugh!
Why does everything look so great on their website?
I don't have it, but I tried it on earlier this week. It isn't too low cut, but the fit was weird. I definitely do not recommend it if you have a long torso. My torso is pretty short and this shirt was not long enough on me. It looked weird because of the ruffles at the side....I think they were about even with my belly button instead of hitting at the hip.
However, if you want to try it, it's a bit low cut but you could probably wear a cami under it.
I agree with Seashells...I love a lot of stuff when I see it on the Anthro website and then when I see it in the store I'm disappointed. They do have some really nice stuff, but I think that a lot of it is very overpriced.
