help??? the ritz???

im going on vacation to the ritz-carlton hotel in tysons corner soon and idk what to wear!!! my mom told me its a really fancy five star hotel and i cant wear anything cheap like my fave sunglasses from claires. she told me minimum coach cuz its kinda cheap. my purse choices are either fendi or bally cross-body bags. which purse brand is more 'classy' or 'fancy' or 'expensive'? and my clothes...i really dont know. i wear alot of american eagle, aeropostale, forever 21, h&m, wet seal, polo, and target. what would be best to wear? something MY AGE, im 12. and shoes...i have some nice sandals, toms, rainbows, and coach converse. so which shoes would be best? [no heels, haha(:]

so to paraphrase, the questions are:
1)which brand is better to wear? fendi or bally?
2)which brand [fendi or bally] is more expensive or classy?
3)what clothes are best to wear? [american eagle, aeropostale, forever 21, h&m, wet seal, polo, target]
3)what type of clothes should i wear? [skirts, shorts, tees, polos, rompers, dresses]
4)what shoes are best? (pick 2) [coach converse, rainbows, sandals, toms]

thanks(: props to best answer!
