Initially bought a 2XL YIANNA Latex Long Torso Waist Trainer for 34inch - torso, 37.5inch - waist and about 42inch - hips, unfortunately it was a size bigger for me that I was able to hook on the 2nd row, immediately. After few days I managed to hook it on the 3rd row (smallest). I've been refunded 80%, advised by seller to repurchase an XL and finally received this Black Breathable Latex (XL) today. Although it's about 1.5inch shorter than the long torso waist trainer and doesn't cover my postpartum belly, it hugs my body well, very comfortable on the 1st eye row. I am looking forward to losing more inches on my midsection from today onwards.
Note: for example, my waistline is 37-38inch and it becomes 33-34inch after 4inch deduction, so I should buy an XL waist trainer since it fits the 32-34inch waistlines. Hope it helps :-)
