With the arrival of the transitional season, oversized basics return to our wardrobes. In reality, they never quite disappear, but the season of orange leaves and has something special. XXL jackets, extra-large sweaters, or shirts with masculine cuts are back. So much so that on TikTok a new viral trend has emerged: basics with a boyfriend effect.
As the name itself suggests, this trend is quite literal. It simply describes those roomy garments that look borrowed from our partners (although you could also raid your brother’s, cousin’s, father’s, or grandfather’s wardrobe). The goal is to pair them with other feminine pieces, such as a short dress, a blouse and a mini-skirt, or a fluid suit.
The result is a hit in any fashion capital. In fact, my French friends spend months playing with these proportions to achieve elegant, current looks with a minimalist edge that is addictive and irresistible. The best part is that, since these pieces are roomy, they never go out of style and they are incredibly comfortable.
