Below: This is my alternative to Bella's striped thermal. The brand is Splendid- Bella's Energie thermal seems to be brown on green, while mine is green on brown... I got mine from ebay.
Below: Bella wears the Energie Thermal in Twilight, while she is wondering where Edward is (According to Jessica the Cullen's are "camping/hiking"). Bella also wears this thermal in the Port Angeles scene while 'prom dress shopping'; and also in the Restaurant scene with Edward.
