Well i live in jeans too just to start it off. what makes ppl tell me "wow, sara thats really cute" is usually a top thats like very unique in a good way. whether its a hollister top that has a different pattern than the usual solid colors or a cute top from delias that a found on sale for $20, the most important thing to remeber when shopping for this stuff is, ask urself, "Would I feel comfortable in this shirt/pants/jacket/etc." Cuz if u gonna wear it to school feeling wow i shouldnt have bought this or wow its tight or theres like patches here and holes there, its not worth ur money.
First off saying that I WORK at a Hollister store in the US. im not gonna say that all a wear is hollister b/c it wouldnt be true. i'm a loyalist to delias, abercrombie, and pacsun.
my favorties from delias are the very cute tops that they have and the uniquely cute t-shirts and hoodies. u could order a free catalog on their website.

hoodies: http://store.delias.com/browse.do?categoryID=753&sidenavTrack=apparel.hoodies
jackets: http://store.delias.com/browse.do?categoryID=1644&sidenavTrack=apparel.jackets (my favorite is the maria trench and ellie cord blazer)
abercrombie i'll admit is on the pricey side but if u can find something u absolutely adore and will wear it more than twice like a hoodie or a tank or tee, or a nice pair of jeans i'd say go for it cuz i know that all the abercrombie in my closet i worn more than once.

always cute to wear a tank over a white or solid colored tee: http://www.abercrombie.com/webapp/wcs/stores/servlet/category1_10051_10901_12270_-1_12203
pac sun the only things i get from there really is tee shirts or hoodies. my favorite is volcom, famous, and roxy. maybe a little pricey at some brands but quality none the less.

and last but not least hollister.
i love hollister, or i wouldnt have applied there for a job and got it... lol
they have very cute laid back stuff that u would feel comfortable in whether its to a house party, bbq, first day of school, last day of school, etc. basically what u pay for its what u get. sometimes things r on the pricier side but nontheless ur getting ur money's worth.
