A faja is a high-compression garment worn snugly against the body, most commonly after procedures like liposuction, tummy tucks, or Brazilian butt lifts. Getting it on correctly, choosing the right size, and knowing how long to wear it all affect both your comfort and your results. Here’s what you need to know.
Getting the Right Size
Fajas run small. Because the fabric is designed for high compression, you should select at least one size above your everyday clothing size. If you fall between two sizes, go up rather than down. A faja that’s too tight doesn’t just feel miserable; it can restrict blood flow and cause unnecessary pressure on healing tissue.
To find your size, you’ll need four measurements:
- Waist: Measure at or slightly above your navel, around the thinnest part of your torso.
- Hips: Measure at the widest point with your legs together.
- Bust (underbust): Wrap the tape just below your breasts and around your back.
- Torso length: Measure from your underbust straight down to your hip bone.
Use these numbers against the manufacturer’s specific size chart, not a generic clothing chart. Every brand runs differently. The garment should feel firm and snug once it’s on, but it should never cause sharp pain or leave deep indentations in your skin.
How to Put on a Faja
High-compression garments are stiff and tight by design, so putting one on takes some patience, especially in the first few weeks when your body is swollen. Step into the faja from the bottom, sliding both legs through the leg openings first. Pull it up gradually, working it over your hips in small increments rather than yanking it all at once. Tugging too aggressively can strain the seams or irritate sensitive skin.
Once the garment is over your hips, begin fastening the hook-and-eye closures from the bottom and work your way up. Starting at the lowest hooks lets you secure the base of the garment before smoothing the fabric upward toward your waist and torso. Adjust the fabric as you go so it sits flat against your body with no bunching or folding. Wrinkled fabric under compression can dig into your skin and create pressure marks.
If your faja has shoulder straps, clip or fasten those last, after the main body of the garment is in place. The whole process gets significantly easier after the first week or two as swelling goes down and you learn the garment’s fit.
How Long to Wear It Each Day
If you’re wearing a faja after surgery, most surgeons recommend wearing it around the clock for the first two to three weeks, removing it only to shower. After that initial period, your doctor may allow you to start tapering, wearing it for fewer hours each day as swelling decreases and your body heals.
The total timeline varies. Most physicians recommend wearing a post-surgical faja for four to eight weeks minimum. A common protocol is to wear a Stage 1 garment (softer, designed for the immediate post-op period) for about three weeks, then transition to a Stage 2 garment (firmer compression) for up to six months. Some people continue wearing a lighter compression garment beyond that for contouring purposes.
If you’re wearing a faja for everyday shaping rather than post-surgical recovery, there’s no strict medical timeline. Many people start with a few hours a day and gradually increase wear time as they get comfortable. Listen to your body: numbness, tingling, or sharp pain means the garment is either too tight or you’ve been wearing it too long without a break.
Sleeping in a Faja
For post-surgical wear, yes, you’ll sleep in it. During the first 12 weeks after a procedure like a BBL, the compression garment needs to stay on overnight. The transferred fat requires continuous support while it integrates into surrounding tissue, and removing the garment too early can compromise your results.
Sleeping position matters. After a BBL, you’ll typically need to sleep face down for the first few weeks to avoid putting pressure on your buttocks. Around week four, you can shift to sleeping on your back, and by week six, side sleeping is usually an option. If you’ve had abdominal or breast surgery, back sleeping is essential to protect your incision sites.
The faja should feel firm overnight but never cause extreme pain. If it becomes noticeably loose after a few weeks, that’s actually a good sign. It means swelling is going down. Rather than buying a completely new garment, you can layer a smaller compression band or corset over the faja to restore targeted pressure where you need it.
Washing and Maintenance
Because you’re wearing this garment nearly all day, keeping it clean is essential. Aim to wash your faja every other day to remove sweat, body fluids, and bacteria. Having two fajas and rotating them makes this much easier.
Always hand wash. Machine washing and hot water break down the compression fabric quickly. Fill a basin with cool water and a gentle detergent, ideally one designed for compression garments. Skip bleach, harsh soaps, and fabric softeners, all of which degrade the elasticity that makes the faja work. Let the garment soak for 10 to 15 minutes, but no longer. Extended soaking weakens the fibers.
After soaking, rinse thoroughly and press out excess water by rolling the faja in a clean towel. Never wring it. Lay it flat to air dry in a shaded, well-ventilated spot. Avoid electric dryers, radiators, irons, and direct sunlight. Heat shrinks the fabric and kills the stretch, while UV light fades the color and degrades the fibers over time. Proper care keeps your faja performing at full compression for months rather than weeks.
Signs Your Faja Doesn’t Fit Right
A well-fitting faja feels like firm, even pressure across the areas it covers. You should be able to breathe normally, sit down without the edges cutting into your thighs, and slide one finger (but not much more) between the garment and your skin.
If you notice skin bulging over the top or bottom edges, the garment is too small. If you can grab a fistful of loose fabric, it’s too large and won’t provide meaningful compression. Rolling or curling at the edges usually means the torso length is wrong for your proportions. Persistent numbness in your legs, difficulty breathing, or skin that looks mottled or discolored underneath the garment are all signs to remove it immediately and reassess your size or compression level.
