Putting on a faja is a slow, methodical process that gets easier with practice. Whether you’re wearing one after surgery or for daily shaping, the technique is the same: step in from the bottom, pull up gradually, and fasten the hooks from the bottom up. Rushing it leads to bunched fabric, uneven compression, and frustration. Here’s exactly how to do it right.
Get the Right Size First
A faja that’s too small will be nearly impossible to close, and one that’s too large won’t provide meaningful compression. You need two measurements: your natural waist (the narrowest point above your belly button) and your hips (the widest point around your buttocks). Use a soft tape measure and stand relaxed. Don’t suck in.
Sizing varies by brand, but as a general reference, a medium typically fits a 28 to 34 inch waist and 38 to 44 inch hips. A large usually covers a 32 to 36 inch waist and 43 to 47 inch hips. Always check the specific brand’s size chart, because a small in one line can overlap with a medium in another. If you’re between sizes and wearing the faja post-surgery, go with the larger size. Swelling in the first few weeks can make a snug fit unbearable.
Prepare Your Skin
High-compression fabric against bare skin for hours at a time can cause chafing, creasing, and irritation. Many people wear a thin comfort slip or seamless undergarment beneath the faja to create a smooth barrier. This also makes the faja easier to slide on because it reduces friction against your skin. Avoid applying lotions, oils, or creams before putting on the garment. These break down the elastic fibers over time and can make the fabric slide out of position.
Step-by-Step: Putting On the Faja
Start with the faja completely unfastened. Gather or scrunch the entire garment in your hands so you can control it as you step in, similar to how you’d scrunch up stockings before pulling them on.
Step in one foot at a time. If your faja has leg panels, pay attention to any anti-roll strips along the bottom edges of the legs. These need to sit flat against your thighs, not folded or curled. Pull the garment up slowly, working it over your calves, then your thighs, then your hips. As you pull upward, check that the seams align with the natural contours of your thighs, hips, and buttocks. Twisted or bunched fabric creates pressure points and visible lines under clothing.
Once the lower half is in place, slide your arms through the armholes and adjust the shoulder straps so they sit comfortably without digging in. Take a moment to smooth the fabric around your armpits, upper stomach, and sides before moving to the closures.
Fastening the Hook-and-Eye Closures
This is the part most people struggle with. The key is to start from the bottom and work your way up. One helpful trick: before you begin at the bottom, temporarily clip the first hook near your bust line just to hold the faja in place. This keeps the garment from shifting while you work the lower hooks.
With the top anchor in place, go back to the very bottom hook and fasten each one moving upward. This approach lets you distribute tension evenly and make small adjustments as you go. If you try to start from the top or the middle, the fabric bunches and the lower hooks become much harder to reach.
Most fajas have multiple columns of hooks, usually two or three rows set at slightly different widths. When you first start wearing the garment, use the outermost (loosest) row. As your body adjusts, or as post-surgical swelling goes down, you can move to the tighter rows. Trying to force the tightest setting on day one is a common mistake that makes the faja uncomfortable and harder to put on.
Post-Surgical Wear Schedule
If you’re wearing a faja after liposuction, a tummy tuck, or a BBL, the garment typically stays on around the clock for one to three weeks, removed only for showering. After that initial period, your surgeon will likely clear you to switch to nighttime-only wear for several more weeks. The exact timeline depends on your procedure and how you’re healing, so follow whatever schedule your surgical team gives you.
For daily shaping or waist training (not post-surgical), there’s no strict medical schedule. Most people build up gradually, starting with a few hours a day and increasing as the garment breaks in and their body adapts.
Common Problems and How to Fix Them
Rolling at the thigh or waist edges is the most frequent complaint. This usually means the garment has shifted during wear. Pull it back into position and make sure the anti-roll strips at the leg openings are lying flat. A comfort slip underneath also reduces rolling.
If the hooks feel impossible to close, you may be fighting too much fabric at once. Lie flat on your back. Gravity spreads your torso slightly and brings the two sides of the closure closer together. Some people also find it easier to fasten the hooks while sitting on the edge of a bed, leaning slightly back.
Skin marks and redness are normal after extended wear, similar to sock lines on your ankles. Deep indentations, numbness, or sharp pain are not normal. These signal the faja is too tight or positioned incorrectly.
Washing and Maintaining Your Faja
A faja worn daily needs to be washed daily, especially post-surgery. Hand washing is ideal: use cold or lukewarm tap water (below 104°F) with a mild detergent that’s free of bleach, fragrances, and dyes. Rinse thoroughly, roll the garment in a towel to press out excess water, and lay it flat to air dry out of direct sunlight. Never wring it out. Twisting damages the elastic fibers that provide compression.
If you machine wash, use a cold, delicate cycle and place the faja inside a lingerie bag. Skip the fabric softener and dryer sheets entirely. Air drying is strongly recommended, but if you must use a dryer, choose the lowest heat setting available. Never dry clean a compression garment. Having two fajas and rotating them makes daily washing practical without leaving you uncovered during the drying time.
