Following an abdominal surgery, I purchased several fajas to help with the swelling. For context, I am 5’7” and 145 pounds. I was swollen on the abdomen and could not even think of trying a size small. I started with XL a week post op. Two weeks post op, a medium fit nice and snug and I was really feelin’ myself. Now 4 weeks post op, a size small fits the absolute best. My swelling is minimal at this point. While I’ve spent a good amount of money on these fajas, I’ve tried several different brands and THIS IS THE ONE. Quality. It’s also dinner right now and I am not sweating bullets in this thing. Highly recommend if you’re trying to contain, recover from a tummy tuck or lipo, or just want to smooth it out. Take the advice though and go smaller, stuff it in, and you’ll notice it fits better over time because your body is actually tightening.
