3.1 Phillip Lim

We're going to go ahead and say it: we think the floral 3.1 Phillip Lim ensemble Selena Gomez wore to Z100's Elvis Duran and the Morning Show in NYC is her coolest yet (we love seeing the sporty side of Selena!). The singer paired this Get It Girl tee ($150) with these relaxed botanical-print pants ($425), then added perfectly crisp Bionda Castana navy and ivory sandals ($584). Her finishing touches — a gold circle necklace and gold watch, both by House of Lavande Vintage — lent just enough shine. Score Selena's entire ensemble to wear together or mix and match the pieces with ones you already own. We love the idea of trying her sleeveless tee with boyfriend jeans and her floral trousers with a chambray or classic white button-down for another variation on Phillip Lim's very cool pieces.

White is an undeniably crisp Spring color, and when you throw white on top of white? Well, it makes for a double dose of freshness. Case in point: Lily Aldridge's latest NYC ensemble, which included Equipment's silky white button-down ($208) and these 3.1 Phillip Lim draped trousers ($375). Equally impressive were the model's add-ons: these adorable Charlotte Olympia kitty cat loafers ($825), Givenchy's black Pandora bag ($2,020), and cat-eye sunglasses. Score Lily's exact pieces below — but first, a few tips on perfecting white on white for day and night. Be sure to also check out more impeccable model street style here.

• Pick the white pieces that feel the most comfortable for you — it can be tees, tanks, jeans, skirts, shorts, etc.
• Like Lily, add nonwhite accessories for contrast. We especially love the mix of white with animal print.
• For an office-appropriate white-on-white look, try tucking a white silky blouse into a white pencil skirt, then finishing off with nude or black pumps.
• To make white work for night, add sexier details like strappy sandals and shiny jewels to dress it up.

Reese Witherspoon's 3.1 Phillip Lim Ava pumps ($179, originally $450) have helped amp up her Spring style, and now it's time they do the same for you — at 60 percent off! (Side note: we love how they share the same name as her daughter.) There are many things we adore about these colorblocked pumps: the two-tone detail makes them stand out among a sea of classic pumps, the mix of fuchsia and burgundy works well for day and night, plus the d'Orsay cut gives them a vintage flair. And, of course, the majorly discounted price tag means they won't break your budget. Win-win in our book. Work Reese's exact pumps into your Spring style, but first, read a few easy tips on how to get the most wear out of them.

• Follow Reese's lead, and dress up your favorite denim by pairing them with your colorblocked pumps. Finish with a chambray top for a fresh denim-on-denim outfit.
• For a classic look, wear these pumps with a little black or white dress for day or night.
• For an edgier evening look, sport your new pumps with leather — it can be a dress, skirt, shorts, or pants.
• For a work-appropriate ensemble, match your pumps with a silky button-down and cropped trousers.
