I personally love this shirt and in my opinion i think that it is the same shirt that she wears underneath the striped henley in the cliff diving scene.
there are some HQ pictures from those above to take a better look ...I also think that it is the same top as in the scene where she is trying to call Jacob!
I don't think it's the same shirt from the cliff dive scene. I think this one's a darker, navy blue. To be honest, until she walked into the light I thought she was wearing black.Here is an option:http://www.chickdowntown.com/viewproduct.asp?ID=114853
This doesn't exactly fit in this post..but heads up to Twilighters! You can get an official replica set of Bella's St. Jude braclet, the turquoise cuff, and the moonstone ring in a box set for around $40 which could be a lot cheaper than buying each of these items indivdually from handmade sellers! The pieces are pretty good quality too!
Old Navy sells shirts that look like the ones she wears here & in the cliff diving scene. They are crazy soft and comfortable, plus it's the same place & type of shirt (Women's Perfect Tees) she wore in the kiss scene in Twilight. :)
I just wanted to say that I think that our theory of it being an old navy perfect tee is pretty good, considering that they seem to like that brand for the twilight films. However, I went to the movie again just last night. I was very interested in the details of this shirt as it would be an essential in your closet. I am fairly certain that there were cuffs at the end of the sleeves, like the AE top pictured above. I would not be surprised if it was in fact the AE top above. AE was used quite frequently on set it seems.
I'm pretty sure that what she wears in the bedroom scene is actually a sweater... I saw that it had a hood when I was watching a video on YouTube....
