Ashley Tisdale is already 30 years old. Can you imagine?

Yeah, the cutie doesn’t look it. I guess we can all blame it on her youthful appearance complete with very so-Cal fashion sense. In fact, for her bash last Friday, the former Disney darling donned a casual getup that was oh-so California summer appropriate.

Ashley wore skimpy daisy dukes, a crop top, and a pair of flat sandals for the pool party. She capped off the mix with stacks of arm party and some really cool eyewear. Altogether, it was an ordinary-looking getup; nothing special, but she look fabulous, nonetheless.

I like Ashley. She seems natural and she never appears as though she’s trying so hard to be stylish. I would spend my birthday in the same getup if I could. Thing is, I don’t have her toned abs so it’s a no-can-do for me.

What about you, would you go with a casual look for a poolside birthday party, or are you the type who would step it up when it comes to birthday style?

Ashley’s crop top — which is actually a reversible bikini top — is from Mara Hofftman. A  similar piece with a different print is available for the taking if you’re interested.

Ashley daisy dukes are from One Teaspoon while her sunglasses are from a label called Krewe. As for her super cool studded thong sandals, they’re from Valentino. The style is a classic, and the label reissues it each season all thanks to a universally flattering thong silhouette complete with studded ankle straps for a touch of edge and flair.

For the gals who like it extra strappy, you may also catch the Valentino double ankle-wrap thong sandals. They come with three instead of two ankle straps, plus more studs, of course.

If you like Ashley’s style, simply wear the sandals with skimpy denim shorts and a crop top, then top off the combo with dramatic sunnnies. For the frugal fashionista, these affordable studded options are worth considering:
