Learn how to get the best fit from the Modibodi SmileyWorld Tie One Piece period swimsuit, with step-by-step tips on sizing, tying, and care.
Quick Answer
For the best fit in the SmileyWorld Tie One Piece, choose your usual Modibodi size, adjust the side ties to your torso, and use the SuperAbsorbency flow for medium to heavy days.
Why the tie design matters for fit
The SmileyWorld Tie One Piece uses side ties instead of fixed seams, which gives you more control over how the suit sits on your hips and torso. This is especially useful if you are between sizes or prefer a higher or lower leg cut.
Because the suit is made for swimming and period protection, the ties also let you loosen or tighten the fit without affecting the absorbent panel placement. That means you can adjust for comfort while keeping the leak-proof coverage where you need it.
Sizing considerations for a one piece
One-piece swimsuits fit differently than bikinis because they cover more of your torso. If you are between sizes, consider your torso length first: if you have a longer torso, you may need to size up to avoid the suit feeling too short in the body.
The SmileyWorld Tie One Piece has adjustable ties, which can help with hip fit, but the torso length is fixed. So if the suit feels tight across the shoulders or crotch, that is a sign you need a larger size, not just a tighter tie.
Absorbency and water use
This style comes with SuperAbsorbency, which holds up to 50 mls or 10 tampons' worth of fluid. That makes it a solid choice for medium to heavy days, both in and out of the water.
Remember that period swimwear absorbs water as well as period fluid. The suit will feel heavier when wet, so a snug fit at the ties is important to keep everything secure while you swim.
How to Get the Best Fit in Your SmileyWorld Tie One Piece
- Measure your torso and hips: Use a soft tape to measure from your shoulder, through your crotch, and back to the same shoulder. Compare that to Modibodi's size chart, and also measure your hips at the widest point. Choose the size that fits both, not just one. If your torso and hip measurements point to different sizes, go with the larger size for comfort.
- Try it on and adjust the side ties: Put the suit on and tighten or loosen the side ties so the suit feels snug but not digging in. The leg opening should sit comfortably without gaping, and the crotch should feel secure against your body. A common mistake is tying too tight, which can cause the suit to ride up. Aim for a secure but comfortable fit.
- Check the absorbent panel placement: Make sure the absorbent panel is centered and covers from front to back. When you move, the panel should stay in place. If it shifts, the suit may be too loose. If the panel moves when you walk or swim, adjust the ties or consider a smaller size.
- Test in water before your period: Wear the suit in a shower or pool to see how it feels when wet. The suit will absorb water, so check that it doesn't sag or chafe. This also helps you get used to the fit before you need it for period protection. If the suit feels too heavy or loose when wet, you may need to tighten the ties or go down a size.
- Care for your swimsuit properly: Rinse the suit in cold water after each swim, and wash it in a mesh bag on a gentle cycle. Avoid wringing or using fabric softeners, as they can break down the absorbent fibers. Proper care extends the life of the suit and keeps the absorbency working effectively.
