The Francine Longline Waistcoat & Wide-Leg Trouser Set is a two-piece set: one longline sleeveless waistcoat and one pair of matching wide-leg trousers, cut from the same fine, flat knit. Two pieces are included, and the set comes in three colors: Forest Green, Chocolate and Navy.
The waistcoat fastens with five polished gold-tone buttons running from the bust to the natural waist, and below the lowest button the front edges hang open. The neckline is a deep collarless V finished with a narrow self-fabric band that carries round to a plain, high, straight back neck. The armholes are cut deep and low enough to show the side of the body, so most shoppers will want a layer underneath. The trousers pull on through a ribbed knit waistband with no fly, button or drawstring, and fall straight and full from the hip to a short vertical slit at each front hem. Neither piece has pockets.
Key features
- Two matching pieces — a sleeveless longline waistcoat and wide-leg trousers, bought together and easy to wear apart.
- Five gold-tone buttons — squarish with rounded corners and a hand-formed facet, set from bust to waist on the waistcoat front.
- Deep V and cut-in armholes — an open collarless neckline with low armholes, so plan on a top or slip underneath.
- Pull-on trousers — a ribbed knit waistband with no visible closure, plus a short slit at each front hem.
- Three colorways — deep Forest Green, warm Chocolate and a true blue Navy, each in a plain, unpatterned knit.

FAQ
How many pieces are in the set?
Two. The longline sleeveless waistcoat and the matching wide-leg trousers come together at one price.
Do I need to wear something under the waistcoat?
Most people will want to. The V is deep and the armholes are cut low enough to expose the side of the body, so a fitted top, bandeau or slip underneath makes it much easier to wear day to day.
How do the trousers fasten?
They have no visible fastening. There is no fly, button or drawstring. The waistband is a ribbed knit band and the trousers pull on.
Are there any pockets?
No. Neither the waistcoat nor the trousers has pockets, front or back.
