Carrying on the C-series refinement: UNIQLO 26SS Intimates debut, the “Youthful Preppy” loungewear is just too soft and cute!

Coming home each day and changing into something comfortable is the perfect ritual for washing away the day’s fatigue. With the rise of the laid-back “Bedcore” aesthetic and casual style, lingerie and loungewear are no longer merely supporting players hidden beneath everyday outfits. UNIQLO understands what budget-conscious women want, and its latest Spring/Summer 2026 collection quietly introduces a new W’s Intimate Collection of women’s intimates and loungewear. Once again designed by creative director Clare Waight Keller, the collection pairs retro florals, checks, and stripes with soft, comfortable fabrics for everyday looks that feel comfortable yet still have a touch of refinement. One look at the preview is enough to make you want the entire collection.

1. Wireless cotton bra: Sweet or cool, with no fuss for everyday wear

For anyone who prioritizes comfort, a wireless bra is an essential part of the wardrobe. Designed by Clare Waight Keller, this women’s wireless cotton bra is versatile enough for sweet or cool looks and easy to wear every day. The collection skips the restrictive feel of traditional bras in favor of soft cotton that gently hugs the skin. Alongside classic cuts, it also includes triangle-cup styles with a distinctly French laid-back feel. Their subtly sexy cut naturally follows the shape of the bust, lending a clean, elegant feel whether worn on its own or beneath a sheer shirt.

2. 24h+ ribbed tank: Easy to style on its own or layered

The heart of this collection is undeniably its youthful, school-inspired feel. Nicknamed the “24h+ tank,” this women’s ribbed tank works for lounging at home, sleeping, or layering under an outfit when heading out. It looks great worn alone or layered, and is so easy to style that you’ll want every color. The collection includes cropped tanks with retro square necklines, along with fine-striped styles that carry a British vintage feel. In a slightly chilly air-conditioned room, simply throw on a ribbed V-neck knit cardigan from the same collection. Leave the buttons slightly undone to reveal a hint of the layer underneath, and you’ve got a stylish preppy look.

3. Cotton boxer shorts: Comfortable with a girlish touch

What would time at home be without a pair of shorts that lets you fully unwind? Nicknamed the “soft and playful shorts,” these women’s cotton boxer shorts offer plenty of comfort along with an easy, girlish feel. Made from soft, skin-friendly fabric, they feature playful retro checks and stripes. Available in burgundy, indigo, blue, and other shades of blue, they bring a cool, lively touch to summer days at home.

4. Cotton loungewear set and wide-leg pants: The ultimate relaxed feel

If you’re looking for a complete laid-back outfit, take a look at the women’s cotton loungewear set. A classic long-sleeved button-up shirt paired with casual pants, in fresh off-white or burgundy, creates an exceptionally relaxed feel.

For those who prefer to mix and match, the women’s ribbed wide-leg easy pants are another option. Their flowing, straight wide-leg cut flatters the legs, while the highly stretchy ribbed fabric makes moving around at home even more comfortable and unrestricted. The women’s underwear collection also offers four cuts at once: boxer, high-rise, mid-rise, and low-rise. High-rise styles offer plenty of coverage, while low-rise styles pair well with low-rise summer pants for a polished touch in the details.
