Mass & Slim works with your body.
Mass & Slim Shapewear Shorts combine supportive shaping with Tourmaline® micro-massage technology, designed to help support circulation, smooth the appearance of cellulite, and help reduce inches over time.
Instead of simply squeezing your body, the fabric gently works with your natural movement—providing both instant shaping and gradual, visible improvements with consistent wear.
Why Thousands of Women Choose Mass & Slim Shorts
Instant Shaping
The high-waisted design smooths the waistline, shapes the hips, and supports the thighs the moment you put them on. The seamless structure sits invisibly under dresses, skirts, pants, and everyday clothing.
Clinically Tested Cellulite Support
In a 30-day third-party clinical study, participants experienced measurable reductions:
- Up to 3.2 cm around the hips
- Up to 2.3 cm around the thighs
For best results, wear your Mass & Slim Shorts 8 hours per day for at least 30 consecutive days.
Tourmaline Micro-Massage Technology
Hundreds of small Tourmaline ceramic beads are embedded directly into the fabric.
As you move throughout your day, these beads create gentle friction against the skin, producing a subtle micro-massage effect that helps support:
• healthy circulation
• lymphatic flow
• reduced fluid retention
• smoother-looking skin over time
Breathable All-Day Comfort
Made with a breathable bamboo-viscose blend that feels soft and lightweight against the skin.
Customers frequently wear Mass & Slim Shorts 8–12 hours daily—under scrubs, office attire, dresses, or everyday clothing.
No rolling. No pinching. No constant adjusting.

What’s the difference between the Grey Mass & Slim Shapewear and the Black Compression Leggings?
TheBlackPurple makes two distinct types of body-shaping garments. Both use the same Tourmaline® micro-massage technology to support circulation, reduce the appearance of cellulite, and help reduce inches over time. The difference is how and where you wear them.
Grey Mass & Slim Shapewear (Shorts, Leggings & Waist Shaper) — worn UNDER your clothes:
- Designed to be completely invisible under any outfit — scrubs, dresses, jeans, and everyday clothing
- Higher elasticity for all-day, flexible comfort that moves with you
- True to U.S. sizing — size up only if you're between sizes
- Best for: all-day layering, work, errands, office wear, and everyday life
Black Mass & Slim Compression Leggings — worn AS outerwear:
- Fully opaque, squat-proof, and gym-ready — designed to be seen, not hidden
- Firmer compression for maximum sculpting and lifting from the waist to the ankle
- Size up one full size from your usual U.S. size
- Best for: workouts, long shifts, managing swelling, or anyone who wants the strongest hold
Not sure which is right for you?
Choose Grey Shapewear if you want comfortable shaping — waist, hips, thighs, or full legs — invisible under your existing wardrobe.
Choose Black Compression Leggings if you want firm, full-leg outerwear compression you can wear to the gym, on errands, or anywhere you'd wear your favourite leggings.
Many of our customers own both — grey for everyday layering under clothes, black for gym days, and long shifts when they want maximum support they can actually be seen in.
Can I wear them all day?
Yes. The breathable bamboo-viscose fabric is designed for extended wear, and many customers wear them 8–12 hours daily.
So comfortable, you can even sleep in them.
Will they make me feel hot?
No. The bamboo-viscose fabric is breathable and cooling, allowing many customers to comfortably wear Mass & Slim Shapewear Shorts daily.
Will they show under my clothes?
No. The seamless, high-waisted design sits smoothly under dresses, skirts, pants, and scrubs.
What if they don’t fit?
We offer 60-day risk-free returns and free size exchanges. If your first pair isn’t the right fit, we’ll help you find the perfect size.
