The “I woke up like this” of tees. With a slouchy shoulder, boxy fit, and soft Tencel blend, this is the kind of throw-on-and-go magic you’ll want in every colour. It’s that good.

The Three Measurements That Matter
Place the tape close under the armhole at the fullest part of your bust. Measure from side seam, around and back to the same side seam.
Keep the tape parallel to the floor — snug but not tight.
Measure at the narrowest point — usually 2–3 cm above your belly button. Place the tape from side seam, around and back.
Exhale naturally before taking the measurement.
Place the tape approximately 20 cm below your natural waistline at the fullest part of your hips. Measure all the way around.
Stand with feet together for the most accurate result.
