Warm weather typically ushers in easy-breezy dressing but this summer's go-to outfits will be basically effortless, thanks to trending one-and-done, loose-fitting silhouettes. Carla Ferrer, a model and architecture student already basking in 80-degree sunshine in Valenica, Spain, provides a tutorial via recent Instagram snaps, featuring lightweight, drawstring-trousers specifically these and these, striped Sezane shirts (above), crochet button-downs (I also LOVE this and this long-sleeved!) and shorts, simple but statement-making and go-with-everything tank tops and puff-sleeve dresses (Farm Rio and Ulla Johnson--use the code MarlienRentmeester10off for 10% off sitewide!).
