Girlfriend Collective's 'Bianca' sports bra is suited for low to medium-impact workouts like yoga or hiking. It's made from stretch recycled-polyester in a one-shoulder shape and has an elasticated underband that offers flexibility and support. Details & Care: • Black stretch recycled-polyester • 79% recycled polyester, 21% spandex • Machine wash Seller's note: Worn maybe 2-3x, then washed and packed. Has very minimal piling on the band that could be shaved away. Other than that, there are no other visible flaws noted during inspection. I ONLY used compostable or reused material during shipping.
