1) A killer pair of stilettos. The higher the better.
2) Mascara. Not just any mascara. The best mascara. DiorShow Mascara to be exact.
3) A great accessory [to the outfit]. Just something to add a little pizazz to the outfit. Doesn't need to be expensive, just has to look fantastic. Like these...
I've worn these out on the town and on the beach in Cabo. And guess what? They were only $5.80 each. Gotta love Forever21.
