I purchased a size equivalent to Japanese 3XL from SHEIN. They are very comfortable to wear, and the elastic waistband stretches a lot, so even those with larger lower bodies can wear them easily. They have a design that makes you look slim, but I wanted beige and they are light pink, so I have no use for them. I only tried them on once. I have attached the size chart from when I purchased them in the second image, so please refer to it.
