Tibi - Cashmere Track Pants - Ivory - XXS/XS

If you follow Tibi's founder Amy Smilovic on Instagram, you know she often uses the term "WOF" to describe pieces that always work "With Out Fail" - such as these track pants. Part of the brand's 'Fundamentals' collection, they're spun from soft cashmere and have a relaxed-leg shape and adjustable ties at the mid-rise waist and tapered cuffs.
