We're always here for an outfit formula, particularly if it comes courtesy of Hailey Bieber. And for her latest trick, the model has concocted a pairing that is simple, sexy and summery, all at the same time (quite a feat). Introducing your latest hot couple: the little dress and the big blazer.

Posting on Instagram, Bieber shared a photo of herself wearing a lingerie-style lace dress by Balenciaga (the little part of the equation) with an oversized blazer from Havre (the big). The mini's naughty streak was counterbalanced to perfection with the slightly school uniform-style blazer (plus the fact that she wore the look with white socks and black loafers). A little bit glamorous, a little bit grungy, it's exactly what you need this summer. Hopefully, you already have both parts in your wardrobe (and if you're not a fan of minis, you can always sub in a slip dress, no sweat).
