Age may only be a number, but there鈥檚 something about turning 30 that just feels so, well, adult. You鈥檝e finally managed to get your sh*t together (for the most part) and can start investing in yourself. Sounds pretty good, right? Whether you鈥檙e turning the big 3-0 soon or slowly creeping toward the milestone, your first order of business should involve stocking up on a few wardrobe essentials (think: an elegant evening clutch, denim that fits like a glove and upgraded versions of your everyday basics). No matter where your sartorial loyalties lie, the 21 pieces below are indispensable additions to any wardrobe.

madewell-jeans

1. Madewell Cruiser Straight Crop Jeans in Shane Wash ($135): If you haven鈥檛 already found *your* denim brand and cut, now is the time to try Madewell鈥檚 straight-leg silhouette. It flatters just about every shape, and the crop length will take you from summer to fall in a flash.

culottes

2. Uterq眉e Burgundy Culottes ($119): Whether you鈥檙e doing the corner office thing or grabbing drinks at a swanky new wine bar, tailored trousers are always a flawless option. Classic black ankle pants are incredibly versatile and timeless, but don鈥檛 be afraid to embrace bolder options, like these Instababe-approved burgundy culottes.

gold-mules

3. Mango Metallic Mule ($40): We love classic ballerinas 鈥 don鈥檛 get us wrong 鈥 but it鈥檚 time to graduate to a pair of steppers that live up to your haute standards (and feel a little more grown up). Start beefing up your lineup with sleek flats with a modern edge, like these swoon-inducing gilded mules.

camisole

4. & Other Stories Slip Top ($55): A classic camisole (skip the cotton styles) will prove itself time and time again 鈥 it鈥檚 the ultimate layering piece. Tucked into jeans and layered underneath a boyfriend blazer, it鈥檚 the basis for a sophisticated after-hours ensemble. Just add chandelier earrings and ankle-strap sandals.

blazer

5. Topshop Slouch Tuxedo Jacket ($125): Your office may not have a strict dress code, but a good blazer will take you well beyond the boardroom. The key is to ensure the perfect fit, so don鈥檛 be afraid to hit up your tailor.

satin-skirt

6. H&M Wrapover Satin Skirt ($40): Pieces that can kick it both on and off-duty are major wins in our book 鈥 and this asymmetric number is no different. The length and clean-cut silhouette make it appropriate for the workplace, while the satin fabric delivers a subtle note of glamour that allows for a flawless after-hours transition.

modern-drop-earrings

7. Modern Weaving Abstract Stacked Loop Earrings ($135): Costume jewelry is great, but you鈥檒l get more mileage out of well-made pieces that can stand the test of time. That doesn鈥檛, of course, mean sticking to pearl drops and diamond studs. These abstract brass stunners are durable, versatile and It girl-approved.

blouse

8. Ann Taylor Cypress Botanical Smocked Ruffle Collar Blouse ($90): A billowy blouse is your best friend when you鈥檙e feeling bloated or just want to put on a polished front without putting in the effort (us, always). Neutrals are always great, but DO mix in a few punchy prints to keep things feeling fresh.

keepsake-dress

9. Keepsake Say You Will Dress ($195): Invest in a fierce frock that can kick it at a variety of occasions and that you鈥檒l be pumped about wearing again and again. Boasting ethereal ruffles and a saucy cold shoulder cut, this navy number is both elegant and cutting edge.

sunglasses

10. Sonix Dafni 56mm Gradient Cat Eye Sunglasses ($98): There鈥檚 a reason every influencer out there owns an arsenal of sunglasses 鈥 they can instantly make even the most timeless pieces feel runway-ready. These quirky cat eye sunnies are personality-packed, yet still manage to nail it in the sophistication department. It also doesn鈥檛 hurt that they come in under $100.

joggers

11. ASOS Deconstructed Cigarette Jogger ($38): Instead of rocking sweats out in public, slip into a pair of tailored joggers that even the likes of Audrey Hepburn would swoon over. The sharp styling keeps your getup feeling elegant, even when you鈥檙e kickin鈥 it on the couch.

belt

12. BCBGMAXAZRIA Faux-Leather Belt ($58): Belts do much more than keep your trousers from falling down to your ankles 鈥 they鈥檙e a fashion statement in their own right, elevating everything from swingy floral dresses to snuggly knit tunics in a cinch.

wrap-dress

13. Reformation Chelsea Dress ($248): There鈥檚 a reason Diane Von Furstenberg鈥檚 wrap dress is still a favorite of fashionable femmes everywhere 鈥 the cut looks downright DDG on everyone. Reformation鈥檚 Chelsea dress brings the same level of wow-factor to the table, but with a slightly more affordable price tag. Here鈥檚 to your new date night, on-duty and wedding guest go-to.

hairclip

14. Matsuura Co. Pearl Inset Claw ($12): We wouldn鈥檛 begrudge you a flower crown 鈥 a real one 鈥 at the festival, but kitschy headpieces and juvenile accessories have got to go. Swap 鈥榚m out for a pearl-inlay clip with goddess vibes to keep that perfectly undone 鈥榙o in check.

gold-sneakers

15. New Balance for J.Crew 620 Sneakers ($80): We love a good pair of statement trainers (the bolder, the better), but classic white or neutral-colored kicks (we鈥檙e partial to these dreamy gold numbers) are a versatile basic that will go with everything in your wardrobe 鈥 LBDs and slick suits included.

wallet

16. Brahmin 鈥淪uri鈥 Zip Around Wallet ($135): Say sayonara to cheapie wallets. Since you鈥檝e left those oops-I-forgot-all-of-my-life-essentials-at-the-bar days behind, go ahead and invest in a sleek new wallet that鈥檒l keep your cards, receipt and other financial swag in check AND double as a classy clutch for after-work drinks or a casual coffee date.

pajama-set

17. Victoria鈥檚 Secret聽The Afterhours Satin Pajama ($72): Treat yo鈥檚elf, girl! Ditch those tired sweats and college tees and slip into a pair of posh satin pajamas instead. But don鈥檛 say we didn鈥檛 warn you: These bad boys will change your whole weekend routine 鈥 the luxe, comfy feel might inspire you to lounge at home all day.

ribbed-turtleneck

18. Babaton Johannes Sweater ($95): Turtlenecks are like the unicorns of the sartorial world 鈥 a little bit weird yet undeniably magical. They look straight-up chic tucked into tailored trousers or a printed pencil skirt, and boast serious layering potential 鈥 have you seen the way they turn up the heat on slip dresses and flirty, summer frocks?

strappy-sandals

19. Louise et Cie 鈥淗yacinth鈥 Ankle Strap Sandal ($129): There鈥檚 a reason strappy sandals are a staple for the red carpet set 鈥 they always look flawless. Whether you prefer them in nude, black or metallic, they鈥檒l look just as fab with boyfriend jeans as they would with a formal gown.

long-gray-check-coat-645x823

20. ASOS Boyfriend Coat in Check Print ($151): There鈥檚 something ridiculously luxe about a longline coat (it doesn鈥檛 hurt that they鈥檝e been spotted on some of the biggest fashion influencers either). As if the cool-factor weren鈥檛 enough, the elongated silhouette makes this checked number the perfect partner to midi skirts and ankle-grazing dresses. Sorry, we鈥檙e not sorry, peacoats.

leather-bag

21. & Other Stories Leather Lady Bag ($145): Every adult needs a trusty tote to shuffle her essential swag from point A to point B. Opt for a style sans logos that鈥檚 durable and elegantly edgy 鈥 basically, this sculptural option above.
