My 21-year-old sister Maya and I have a lot in common despite our eight-year age gap, but one of the things we bond over the most is our deep love of summer—and summer fashion. However, since this is her first summer with a nine-to-five corporate internship, she’s had to learn how to navigate getting dressed for the office while still staying true to her cool Gen Z taste. That’s where J.Crew comes in.

My mom and I have been wearing J.Crew for years, but it’s only recently that Maya has come to appreciate the Meghan Markle-worn mall brand’s vast selection of stylish staples. Not only does J.Crew take the stress out of finding cute and comfy work clothes, but the versatile pieces can easily be paired with accessories that allow her to show off her distinct sense of style. The best part? J.Crew is having a huge end-of-season sale on summer fashion with double discounts on previously marked down items.

Keep scrolling to snag up to 84 percent off on airy midi dresses, lightweight linen, and more—just remember to use the code on applicable styles.

Airy midi dresses like this Drop Waist Mixy Dress are essential to staying cool in the summer while keeping your look office-appropriate. Available in black, white, and electric blue, this effortlessly chic dress has a comfortable stretchy cotton bodice and trendy drop waist silhouette.

Though not part of the sale-on-sale promotion, the New Capitaine Irish Linen Shirt is still majorly marked down from its original price of $98—and it’s my sister’s favorite work top. (She has it in three colors.) Made from breathable, high-quality linen, this polished shirt goes with everything from jeans to tailored Bermuda shorts to maxi skirts.

Since the air conditioning at my office is always on full blast, I often prefer to wear long sleeves or a sweater, even on hot days. With roomy sleeves and an ultra-lightweight feel, the Ciel Striped Cotton Poplin Top provides fuller coverage but still conveys a summery vibe (not to mention the discounted price is unbeatable at just $16).

On sale for 84 percent off with the code , the Linen Cotton Blend Tie-Back Midi Dress is the kind of versatile dress you’ll find yourself reaching for at least once a week. You can style it with a cardigan and ballet flats for the office, sneakers for Sunday brunch, or strappy sandals for a night out.

Fine Rib Short-Sleeve T-Shirt

Everyone needs a classic tee that they can tuck into trousers for work or pair with baggy jean shorts and flip-flops on the weekend, and the Fine Rib Short-Sleeve T-Shirt checks off all the boxes. Marked down to less than $15, it’s soft, flattering, and perfectly fitted.
