Scrolling online retailers might not be top of mind when the mercury rises, but, ask any Vogue editor, and they will tell you that the summer sale period is one of the best opportunities to invest in wardrobe staples. Luckily, Mytheresa’s summer sale boasts a variety of elevated basics and investment buys, with discounts of up to 70 percent. You can also expect to find gems from past seasons at a purse-friendly price points: Khaite’s perfectly slouchy leather jacket and Sacai’s utility bomber are both at the top of my list.
