The Serenity Scrunch Shorts 4" in Black are highly praised for their flattering look, buttery soft feel, and amazing quality. Customers appreciate the perfect length, great material, and the scrunch feature that prevents riding up. While most find the fit and fabric excellent, there are mixed opinions on sizing.

"I’m absolutely in love with the Chilli color! It’s the perfect shade of red—vibrant, flattering, and even prettier in person. It makes every outfit look more stylish and really stands out in the gym. If you’re thinking about getting this color, don’t hesitate. It’s gorgeous!"

"These shorts are such a standout! The scrunch detail is super flattering and gives the perfect sculpted look, while the high-waisted fit feels really supportive and secure. The fabric is soft, stretchy, and comfortable, and the no front seam makes them feel so seamless to wear. The hidden waistband pocket is such a handy bonus too."
