I think you look adorable in both styles.
Yes, rolling your jeans is stumpifying (a new word to add to my vocabulary) on most of us, but it's a casual look, so it's okay to look a little less majestic. Angie's advice about wearing a straight jean and higher vamped booties will elongate your look.
But, really, you do look great both ways.
Uh-oh, I feel the urge to step up onto my soapbox: I like to remind the women I work with that we infuse our personalities and our unique body shapes into the clothes we wear. The result is that a particular fashion trend will look completely different from one woman to the next, as it should! To me, that's the fun in fashion -- creating my own unique look out of even the most ubiquitous pair of jeans or cardigan sweater!
Remember to infuse YOU into your outfits. It's not about trends, it's about style.
