Before you ask

3 doubts.
3 answers.

🪑 Does it open when I sit down?No. It stays closed when you sit, bend or move.

🤫 Can you feel it? Is it uncomfortable?No. It's sewn so it doesn't press or scratch: you won't feel it sitting or walking.

👖 How's the fit? Is it stretchy?Defined waist and hips, straight regular-fit leg. The fabric is 97% cotton and 3% elastane: it hugs your curves and moves with you.

How it fits

03 The detail

one zip.
all the difference.

Close-up of Retro Zip: a hand opens the back zip, which runs all the way down the back

It runs all the way down the back, from the waist down. It really opens: you decide how much, and when. Closed, it's a clean pair of jeans; open, it's the detail that turns every head.
