Satin Sleep Set. Dusty Rose
N° 01

Satin Sleep Set. Dusty Rose

Contact us →

Button-front top with a relaxed collar and wide-leg trousers in 19-momme satin. The dusty rose colorway is a warm blush with a slight grey undertone. It photographs pink but reads more muted in person. Comes with a matching satin scrunchie.

Satin Sleep Set. Midnight Navy
N° 02

Satin Sleep Set. Midnight Navy

Contact us →

The same 19-momme satin cut in a deep navy that works as well under a robe as it does on its own. The trousers have a wide elastic waistband and two side pockets. A perennial favourite that returns every autumn.

Brushed Cotton Lounge Set. Oatmeal
N° 03

Brushed Cotton Lounge Set. Oatmeal

Heavyweight brushed cotton in a warm oatmeal tone, milled in Aichi. The top is a relaxed crew-neck with dropped shoulders; the trousers have a wide-leg cut and a drawstring waist. Gets noticeably softer after the first three washes.

Brushed Cotton Lounge Set. Charcoal
N° 04

Brushed Cotton Lounge Set. Charcoal

Contact us →

The same Aichi brushed cotton in a deep charcoal. A slightly heavier weight than the oatmeal. The dye process adds a touch of density to the fabric. Works well as a base layer under the waffle robe on cold mornings.

Waffle Knit Robe. Ivory
N° 05

Waffle Knit Robe. Ivory

Contact us →

Full-length robe in Japanese waffle-weave cotton. Deep side pockets, a self-tie belt, and a collar that holds its shape. Cut generously. Fits comfortably over the satin sleep set or the brushed cotton lounge set.

¥9,600
Ribbed Lounge Set. Sage
N° 06

Ribbed Lounge Set. Sage

Contact us →

Matching top and wide-leg pants in a ribbed cotton-modal blend. The sage green is a muted, slightly dusty tone that pairs well with the ivory robe. The modal content keeps the fabric from clinging and adds a subtle drape.
