ONI drew this pattern from a blank sheet. Rather than adapting one of its men's blocks, the brand built the L720 for a woman's body from the start — balancing the proportions of waist and rise, and placing the back pockets where they give a clean, vintage line rather than where a scaled-down men's pattern would leave them. It is the third ONI Ladies capsule, and the care in the drafting shows in how the jeans sit.

The denim is a 12oz selvedge low tension woven on vintage shuttle looms from a mix of yarns in different thicknesses, which gives the cloth a light crunch and a hand that is firm yet supple: the texture and substance of proper Japanese denim, at a weight that wears easily all day. It comes one-washed, ready to wear.

The cut is a wide straight with a high rise and a generous, straight leg from the thigh to the hem — relaxed and easy to wear, with none of the character stripped out. Construction is full ONI: custom copper doughnut buttons on a button fly, original punched rivets, a cowhide leather patch and the selvedge ID at the outseam, plus the women's line's quiet signature — purple thread at the coin-pocket opening and the inner bar tacks of the back pockets. 100% cotton. Made in Japan.

ONI makes the L720 in two versions, zip fly and button fly, and we stock the button-fly L720-12B. It is the more traditional construction — the one on every vintage pair this pattern looks back to — and the one that ages best: a button fly keeps the front flat and clean, never fails the way a zip can, and its placket fades and softens along with the rest of the jeans.

Fit Notes: This model fits true to size — we recommend taking your usual size. ONI's women's sizes run 0–4; as a guide, a size 1 measures 27.2" at the waist and corresponds roughly to a 25–26 in American brands, a size 2 (28.3") to a 26–27, and so on. The cut is a wide straight with a high rise and a generous, straight leg from the thigh to an 8.3" opening. The denim has been one-washed, so no further shrinkage is expected. With regular wear, the waistband will stretch approximately 1 inch, allowing the fit to settle comfortably over time. We don't recommend sizing down, as starting too tight may cause discomfort and alter the intended fit of the garment. As always, we strongly recommend checking our size chart to find your perfect size.
