FIO bikini bottoms slipping? Learn the likely causes and simple fixes to keep them in place, plus when to size up or choose a different style.

Quick Answer

If your FIO bikini bottoms slip, the fix is usually a combination of choosing the right size, adjusting how you wear them, and checking the fabric condition. If they still slip after trying these fixes, consider a different coverage style.

Why FIO Bottoms Slip

FIO bikini bottoms are designed with a classic medium coverage and a high-cut leg, which can shift if the fit isn't snug enough. The seamless finish and double-lined sustainable fabric provide comfort, but they also mean the fabric has a smooth surface that can move more easily on the skin, especially when wet.

Slipping often happens because the size is too large, the leg opening is too loose, or the fabric has stretched over time. Since FIO bottoms are double lined, they hold their shape well, but no bikini bottom is immune to movement if the fit isn't right.

When to Consider a Different Style

If you've tried the fixes below and your FIO bottoms still slip, it may be that the medium coverage and high-cut leg don't match your body shape. In that case, look for bikini bottoms with a higher coverage back or a tie-side style that lets you adjust the fit. Clearance FIO bottoms are a great value, but only if they actually stay in place for you.

Diagnose and Fix FIO Bottoms Slipping

Symptom: Your FIO bottoms slide down or shift during wear, especially when wet.
Likely Cause: The most common cause is a size too large or a leg opening that's too loose. Fabric can also stretch slightly over time, reducing the grip. Check the fit against the size chart and consider if the bottoms have stretched from use.
Corrective Action: First, try adjusting the placement on your hips—sometimes a slight repositioning helps. If that doesn't work, size down for a snugger fit. If the bottoms are old or stretched, replace them with a new pair of FIO Bottoms. After adjusting, do a quick test: move around and see if they stay in place.
When to Stop or Choose Another Option: If you've sized down and adjusted but the bottoms still slip, the style may not suit your body shape. Consider a different coverage or a tie-side style for a more customizable fit. Don't settle for a slipping bottom—choose a style that stays put.

FIO Bottoms at a Glance

FIO Bottoms [Clearance]: Classic medium coverage bottoms with a high-cut leg and seamless finish. The high-cut leg can make slipping more noticeable if the fit isn't snug, so focus on getting the right size.

FIO Bottoms: Double lined using sustainable fabric made with REPREVE® from recycled plastic bottles. The double lining helps the bottoms hold their shape, but it also means the fabric has less stretch, so sizing up might be necessary if they feel tight or slip down.
