Made in London, United Kingdom, the Gia Tuxedo Trouser is the perfect day to night choice. Her real standout is the contrast matte stripe to the outer legs which provides a flattering and leg lengthening illusion.
Crafted from highly luxurious 30 momme ivory silk, they feel exceptional against the skin and provides additional coverage as nobody wants their undergarments to be doing the talking.
The flat waistband to the front provides a clean and flattering finish, whilst the elasticated back waistband provides comfort and a perfect fit. Designed to sit high on the waist, they cover a multitude of sins and elongate the legs for a perfect wear.
The wide leg falls straight from the hip for a flattering and elegant look which is perfect for daytime, the most luxurious of lounging, or in their perfect setting, dressed up for evening glamour.
Finished to the inside with a double French seam to the stripe, they are almost as beautiful inside as they are to the out. This provides the ultimate comfort, and durability. Pin hems to trouser hem create a delicate, luxury finish.
Please note that separates are sold individually. The Styling Edit below suggests the perfect pairings.
