This Dress Trend Plus Closed-Toe Flats in This Color Is *the* Outfit of Summer 2026
Shop the coolest combination of the season.
There are few things chicer than an Elsa Hosk outfit. Any fashion editor can confirm. She often combines multiple of-the-moment trends into one outfit and does so in the most effortless of ways. The latest summer trends she combined made for an easy outfit I highly recommend copying.
For starters, the summer 2026 dress trend Hosk wore was a sleep dress. In case you're wondering why, exactly, people are wearing sleep dresses outside, let me explain. It's basically a term given to loose-fitting, unstructured summer dresses with pretty, vintage-inspired details such as ruffled trims, bows, and eyelets. If you were to actually sleep in a dress, this style would be a good one to do so in. They're often white (as Hosk's was) but certainly don't need to be.
With her puff-sleeve sleep dress, Hosk wore the closed-toe shoe trend (sorry, sandals) I want to make sure is on your radar: bright blue flats. It may seem a bit specific, but ocean-adjacent shades such as aquamarine and cerulean are a major colour theme this summer, and flat shoes are one of the forms in which people are embracing it.
