Shop Black Activewear for Women
Why Black and Why This Fabric
Black activewear is not a trend. It is the default choice for women who want to move without thinking about what they are wearing. The question is not whether to buy black activewear. It is which black activewear is worth buying. Bellissima's answer is a single fabric: 92% TENCEL Lyocell and 8% spandex. The TENCEL Lyocell fiber is produced by Lenzing AG from sustainably sourced wood pulp using a closed-loop manufacturing process that recovers over 99% of the solvent used in production. The fiber carries OEKO-TEX Standard 100 certification at the fiber level. In black, TENCEL Lyocell has a depth and drape that synthetic fabrics in the same colour do not replicate. Polyester black tends toward a flat, slightly shiny surface. TENCEL Lyocell black has a matte, fabric-forward finish that reads as considered rather than athletic.
Four Pieces Built Around One Colour
The Sempre Leggings are 240 GSM, high-waisted with a V-back waistband, 27.5 inch inseam, diamond crotch gusset, and laser-cut hem. Fully opaque. Squat-proof. The Sempre Shorts are 240 GSM, high-waisted with the same V-back design, 6 inch inseam, and diamond crotch gusset. The Sempre Twist Bra has a V-cut front, a fabric twist at the back, a straight bottom hem, and is double-layered with removable EVA foam pads. The Sempre Halter Bra is backless with a halterneck front, a lower chest line, and removable EVA foam pads. All four pieces are black. All four are made from the same TENCEL Lyocell blend. All four are available in XS through XL.
What Black Activewear in TENCEL Is Best For
Yoga, pilates, barre, reformer, walking, and low-impact training. The 240 GSM fabric weight delivers opacity that holds across the full range of these movements. For sustained high-intensity formats such as running, HIIT, or hot yoga at 105 degrees Fahrenheit, synthetic technical fabrics are more engineered for the output level. Bellissima's black activewear does not position for those use cases and does not need to. In the low to moderate intensity movement space, this collection has no equivalent in natural fiber.
Frequently Asked Questions
Is the black colour fully opaque?
Yes. The Sempre Leggings and Sempre Shorts are 240 GSM and fully opaque in all positions, including deep squats and inversions. The fabric does not lighten or become sheer under stretch.
What fabric is this black activewear made from?
92% TENCEL Lyocell and 8% spandex. TENCEL Lyocell is a natural cellulosic fiber produced from wood pulp by Lenzing AG. It carries OEKO-TEX Standard 100 certification at the fiber level. The finished garments do not currently hold a separate finished-product OEKO-TEX certification.
Does the black colour fade with washing?
TENCEL Lyocell holds dye well due to its cellular structure, which allows for deeper and more even dye penetration than synthetic fibers. Cold water washing and air or low-heat drying preserve colour and fiber integrity longest.
What activities are these designed for?
Yoga, pilates, barre, reformer, walking, and low-impact training. Not designed for running, HIIT, spin, or hot yoga at elevated temperatures.
Are these non-toxic?
The fiber base is TENCEL Lyocell with OEKO-TEX Standard 100 certification at the fiber level. No PFAS treatments. No petroleum-derived synthetic fiber base beyond the 8% spandex. Microplastic-free and plastic-free claims cannot be made due to the spandex content.
Is all the activewear black only?
Yes. Bellissima launches in black only. Black is the intentional choice, not a limitation. Additional colours may follow.
