like wearing air, apparently$156
one size, very stretchy waist$192.20Short version: start with MUJI’s $39.90 double gauze set, 100% cotton and sold on MUJI’s US site. Want plush instead? Gelato Pique is your brand, and it has a US store too. Peach John only delivers in Japan, and tutuanna takes an extra step through an overseas cart.
Japanese loungewear is all about the fabric: airy cotton gauze, fluffy knits and stretchy waffle. Here are five brands worth knowing, and how to get each one in the US:
- On a US site: MUJI, Gelato Pique and SNIDEL, whose US store ships to US addresses
- Through an overseas cart: tutuanna
- Japan-only delivery: Peach John
1. MUJI, for cotton that costs less than dinner
If you only buy one thing, make it this. MUJI puts the fabric right in the product name, so you always know what you’re getting.
- The Double Gauze Loungewear Set is $39.90, with a 100% cotton body. Our first buy.
- The Double Gauze Lounge Pants are $24.90, a cheap way to test the fabric.
- Run hot at night? MUJI says its gauze pants soak up sweat to keep you cool. These are yours.
2. Gelato Pique, when soft is the whole point
The plush one. The brand says its Airy Moco knit feels like wearing air, with a fluffy, baked-sponge texture. (Best product description on this list, by a mile.)
- Expect to spend about $80 a piece, the store’s median price.
- The NY Food Printed Long Pants are $44.40. That’s the easy way in.
- Heads-up: the Peach Collection set is polyester and nylon, so read the material line if you want cotton.
3. SNIDEL HOME, cartoon prints for the couch
Looney Tunes and Sanrio, made for lounging. SNIDEL’s US store ships to US addresses, territories and APO/FPO.
- Tweety Bird Lounge Shorts: $87.30
- My Melody Jacquard Knit Shorts, from mainline SNIDEL: $70. The better deal of the two.
4. tutuanna, cotton pajamas worth the extra step
No US store, but visit from outside Japan and a WorldShopping cart pops up on its own. It buys the piece for you and ships it abroad.
- The pick: a 100% cotton relax pajama with a “melt-away” feel, now in new colors
- Heads-up, you’ll pay twice: the product plus Japanese shipping first, then international shipping and fees once your parcel moves
5. Peach John, look but don’t cart (yet)
Cute, but Peach John only delivers within Japan. The fun find is a rib-knit pajama with a built-in cup, named for “one-mile” wear. Bookmark it for a Tokyo trip.
The fabric decoder
- Double gauze: two thin layers of cotton, airy and soft. MUJI and tutuanna both use it
- Airy Moco and Smoothie: Gelato Pique’s knit names. Airy Moco is the fluffy, baked-sponge one; Smoothie shows up in names like the Smoothie Lite Aran Pants
- Waffle: textured and stretchy, MUJI’s warm-night pick
- One-mile wear (ワンマイルウエア): clothes you can wear within about a mile of home, halfway between loungewear and going out
- Room wear (ルームウェア): what Japanese stores call loungewear
- F: “free size.” Check the inches: Gelato Pique’s F shorts stretch from a 26.4 to 40.2 in waist
Like the sound of these fabrics but not the overseas cart? Amazon has a rib-knit lounge set and a cotton gauze pajama set:
So, what should you buy?
- Just one thing: the MUJI gauze set
- Soft over everything: anything Airy Moco from Gelato Pique
- Cartoon prints, easy shipping: SNIDEL HOME
- A Japan-only print has your heart: tutuanna, with the second bill in mind
