Why Do Swimsuit Bottoms Get Saggy?
Poor-quality fabric
It is possible to find a poor-quality swimsuit with a visually appealing design. However, if your bikini includes more than 70 percent nylon, it can stretch faster than others.
Unfortunately, there is only a short-term solution in this circumstance since the bikini will stretch overtime again, making the cloth even more translucent. So, we recommend just selecting a denser cloth.
Inappropriate usage
You should wear sports swimwear when surfing or participating in water sports. For instance, the suit may droop if you use the same swimwear or pull the bikini up too high for different activities.
Also, in some cases (in a swimming pool), it is advisable to use indoor swimwear. However, you may utilize a distinguished one for relaxing and sunbathing around an outdoor pool. Remember that if you use the same swimwear for many activities, it can wear out significantly faster.
Staying fit
Purchasing a bikini when you were overweight than when you are now is more likely to cause this. Even if you become better or lose weight, your bikini form doesn't change.

Here’re six suggestions for repairing sagging swimsuit bottoms:
1. Make the waist elastic
It is a straightforward procedure. Begin by making a lining for an elastic band that will be installed along your waistband of swimsuit bottoms. Next, cut it shorter than a waistline to make it more snug-fitting.
Remember that don't make it too tight since you won't want your swimwear to be see-through and uncomfy.
2. Tie the drawstrings around the waist.
What should you do if your bikini bottoms begin to sag?
First, you will construct a lining around your waistband of swimsuit bottoms, just as you did with the first way. Still, attach drawstrings instead of an elastic band. As a result, you may knot your swimsuit bottoms together and hold them.
In addition, tie an indeed pin to make things easier. Let’s refer to this video:
3. Obtain matching straps
Ensure that the material you choose is the same as the one used to make your swimwear. Put one piece to one side of your swimsuit and the other to the other, which aids in the transformation of the swimsuit into tie-style swimwear.
4. Scrunch the bottoms up
Another clever idea: scrunch up the bottoms of your swimsuit. This can be done by making a ruffled design or Fold-over style, and it's one way to make a droopy bikini bottom seem more uplifted!
It's the most successful & widely used method for repairing droopy swimsuit bottoms. However, it's not very widely known.
So these are the detailed instructions.
Choose a matching thread. Tie a few knots, feed it through the needle hole, and begin sewing.
Start by making two equally sized holes in the rear of your suit bottom. This will help even out any differences between butt cheeks and look great for everyone!
Thread the needle through both layers of fabric, about one centimeter from where you want to start. Pinch it between your thumb & index finger.
Once again, thread the needle through two pieces of fabric at an angle, leaving only six inches on each side before poking down again. This time, do not push straight into what is already there because it will result in very noticeable creases in your sewing project.
Continue scrunching 4-5 times more. Finally, when you're 1,5 inches from the top, come to a halt. Also, dodge tugging too tightly during the scrunching process.
When you're done with the scrunches, pull that thread back through-hole and repeat this step three or four times. This will keep them from falling out.
You're done! Just knot the end of the thread to the head of a thread.
5. Resize the bikini bottoms
This one is a bit tough since you might change your swimwear into something unwearable if not done correctly. In this case, fundamental awareness of tailoring abilities would help you a lot here.
First, you must cut your suit bottoms then stitch the ripped-up parts back together.
To avoid spoiling your bikini, take accurate measurements at least 2 times before cutting. This way, you won't feel pressured to replace it if you experience problems.
Take accurate measurements of your hips, waist, and other body parts. In addition, because weight swings are a natural process, you should always give some wiggle space for future changes.

6. Sew the waist
This is a quick and easy way to fix droopy bikini bottoms. First, you need to fold the waistband area and stitch it to fit your waist to avoid gaps or holes.
However, sewing too tightly may cause the stitches to come undone at an inconvenient moment. In general, it is a really handy strategy even if you gain weight in the coming year.
The Comprehensive Instructions For Repairing A Sagging Swimsuit Bottom
You only need a needle & thread to get started, as well as a droopy, ill-fitting bikini bottom.
Note: if you have prior experience with basic stitching, go directly to step 2.
The following is a step-by-step guide:
Step 1: Choose a thread hue that complements your swimwear. Knots are not only something you should be aware of when trying clothes; they can also help keep them from coming undone! Thread the thread through a needle hole, then make a knot at one end.
You may wish to tie numerous knots in one spot, as merely 1 or 2 knots may slide through a swimwear fabric. Allow yourself around 10 inches of cotton to ensure you don't run out (some fabrics require more length than others).
Step 2: Start approximately halfway down the back of a swimwear bottom. Make sure it's also in the middle of the breadth of the bottom. Besides, it should align with how wide or narrow you want each cheek to appear.
Step 3: When you've found the center, thread your needle through a cloth coming from the inside of the bikini so that the end kink points within.
Step 4: Measure out one centimeter and re-poke your needle into the cloth, this time from outside. Again, pull the thread tight, then you will hear a crunching sound.
Step 5: Go up one more stitch. Take care not to pull tight or break any thread. Make sure that you get all six stitches nice and tidy with no gaps between them.
Step 6: By doing four to six "scrunches" (rely on how bouncy you want your butt) and doubling the stitches previously created to strengthen them. This is usually done 3 or 4 times for good measure to don't get undone!
Step 7: Now tie a knot at both ends of the thread before finishing off with another bowline knot — which will keep everything stable in place while also making sure there are no loose ends. Of course, knots can also keep things exciting and varied, so I like my knots accordingly!
How To Change Bathing Suit Straps?
If the straps on your suit are too loose, they may cause you to look like an underwear model with a droopy bottom. Modifying a strap is easy to ensure that your swimsuit fits perfectly.
Fortunately, modifying a strap is a simple process. So to fix this problem, there are only two solutions: modify or adjust it to fit correctly!
If your bikini has a shoulder seam, let's try this simple method to fix it.
- Step 1: You will need some fabric scissors and a seam ripper. The first step in fixing it up will be removing all of those pesky little tabs on either side.
- Step 2: Wear the suit to make sure it fits. Play with straps until you find your perfect fit and secure them in place using pins or clips. Then sit down while wearing this garment for any necessary adjustments to not dig into shoulders anymore!
- Step 3: Sew your strap seams to make them as comfortable on the fabric of one side as they are off. Ensure you take care when sewing so that everything stays flat and even for an easy put-on/take-off motion!
- Step 4: Cut off all excess fabric, then complete with a zigzag stitch.

It's nearly impossible to make your swimsuit bigger unless it's old enough to have started sagging.
In addition, the fabric in a suit is so thin that there are no seams allowances in contrast to clothes with built-in seams that can be loosened up to allow extra room.
If you want more space than these measures provide, then creative thinking may help; but know this first: suits don't have much give!
Some individuals may not like the idea of adding panels to their swimwear, but I find them very fashionable. They give more "breathing room," They are great for hiding places you don't want everyone looking at!
Choose a fabric with a similar amount of stretch for swimwear that's as daring (or subtle) on your figure.
In addition, you can choose 2-way fabrics for their bold patterns and figures or go for a 4-way stretch if you want to stay hidden under clothes without showing too much skin. This ideal will make everything smoother!
Cutting a panel to add comfort is easy and takes little time. Cut along the seam of your bikini, pin it in place so that you don't stitch through both layers at once (this can cause undesirable puckers).
Then sew carefully over these stitches with tiny serrated sewing needles or pins for an added touch on top!
Tips For Caring & Preserving For Your Bathing Suit Bottoms From Sagging

You should be aware that you can improve the shape-retention capacity of your bathing suit. Let's keep the following instructions in mind.
The elasticity of your bathing suit will decrease over time due to the oil found in tanning formulas. It interferes with the fabric's shape.
Washing your bikini immediately after swimming is best for its longevity. Alternatively, remember to rinse it to remove salt & minerals.
Additionally, the chlorine in swimming pools impacts the stretchability of the bathing suits, causing them to sag over time.
To avoid wrinkles, always wash your bikini in cold water. If you're using the machine, it's not as environmentally friendly as hand-washing. Remember to use a gentle cycle with no spin option on the drying rack or hang outside to dry. Additionally, don't forget to put it inside a mesh bag before storing away!
Similarly, do not put the swimsuit in a dryer, as this will cause the elasticity to wear out. Instead, hang it up to dry.
