How do I choose the right size?
How do I choose the right size?
We recommend checking the size chart on the product page before ordering. If you’re between two sizes, we suggest selecting the larger size for the best fit.
Can I wash and reuse Guilly panties?
Can I wash and reuse Guilly panties?
Yes, Guilly shapewear is reusable. Rinse after use and machine wash on a gentle cycle (below 40°C), separately to keep colors vibrant. Avoid fabric softeners, bleach, and dryers to maintain lasting performance.
Does HighSlim™ focus more on slimming or on comfort?
