Ah, the summer sales. While they can often receive a lukewarm reception when our bank accounts feel a tad fried, they're the best way to save money on new season essentials. Designer buys are always worth spending more money on; it's all about investing in quality pieces that'll last you a lifetime. And there's one place in particular that's caught our eye for making these wise investments at this time of the year: Mytheresa.com. Mytheresa.com has hundreds of designer brands at up to 50% off, and with over 25,417 pieces available (last time we checked), our fashion editors have filtered out the very best bits (trust us—it was so worth it). It's all about those timeless, clever pieces you'll love and look after for the rest of time. From leather bags and great-fitting jeans to sandals we're confident will never date, we looked to the likes of Acne Studios, Chloé, Tibi and Isabel Marant to help us create our easy-to-shop edit of approved items. Scroll down to for the 21 best luxury basics you should buy in the Mytheresa.com sale before they inevitably sell out. Go, go, go!
