So popular they’re sold out: MUJI boxer shorts, the “just-right comfy” piece you’ll want to wear every day

Lately, a seemingly simple pair of MUJI “boxer shorts” has unexpectedly become a much-discussed item on Threads, Xiaohongshu, and in everyday outfit posts. No logo, no flashy design; at first glance, they even seem a little “too ordinary.” Yet women who value a sense of quality in everyday life keep recommending them. Perhaps that’s exactly what makes them so MUJI: understated, yet once you wear them, there’s no going back.

The item that has gone viral is MUJI’s “No Side Seam Double Gauze Boxer Shorts,” made from organic cotton and designed to feel soft, breathable, and gentle against the skin. Unlike the constricting designs often found in close-fitting underwear, the seamless sides make them feel lighter and reduce uncomfortable friction against the skin, so they are almost unnoticeable when worn. The fit is another key part of their appeal. With a relaxed silhouette that falls somewhere between lounge shorts and underwear, they can be worn on their own or as part of a loungewear outfit. Rather than emphasizing curves like traditional underwear, they give the body more room and put comfort first.

Their popularity among fashionable women also reflects a broader shift: people are starting to redefine what makes clothes look good. Rather than prioritizing tight, shaping, or deliberately sexy pieces, more people care about whether something is comfortable, suitable for long hours of everyday wear, and looks natural and relaxed. MUJI’s boxer shorts happen to meet all of these needs. Soft colors, simple stripes, and lightweight fabric create an everyday sense of style without needing much coordination, speaking to today’s expectations for “quality in everyday life.” When comfort becomes a style rather than a compromise, pieces like these naturally stay in rotation. Perhaps true style has never been about being unusual, but about the things you want to wear every day.

They’re currently sold out on the official website, so stay tuned for news on whether the official website will restock them!
