Sizing Answer

For a 24-week bump around 100 cm, the most reliable approach is to choose maternity sizing designed for belly support, then adjust if you’re between sizes. In practice, start with the maternity size that aligns with your pre-pregnancy size, and size up if you’re between options or if you want extra belly room for comfort and movement. Since sciatic pain is a factor, prioritize the belly panel and waistband comfort over a snug feel across the hips or thighs. If you’re ever unsure between two sizes, choosing the larger will generally improve sit-to-stand transitions and long periods of sitting or lying down.

How It Fits (in real terms)

Our 7/8 Body Shapewear Leggings are designed to sit comfortably under and around the belly with a high, soft waistband that anchors the garment without digging in. The 7/8 length typically falls just above or at the ankle for most heights, offering a flattering silhouette that still keeps the knee and calf free for movement. The belly panel provides gentle compression and support, which can help ease pressure from sciatic nerve irritation when you’re seated or transitioning from sit to stand. The fabric is intended to be breathable and stretchable, so the legging moves with you whether you’re lounging at home, commuting, or running a casual errand.

What that means for you given your 24 weeks and a ~100 cm bump:

Belly support first: Look for a high, soft waistband that sits above the belly. This helps stabilize the bump without pressing on the scar/nerve areas.
Comfort during sitting and lying down: A gentle, even compression around the abdomen and around the hips reduces friction and helps reduce pain during long periods of rest.
Out-of-house readiness: The 7/8 length and pockets add practical wearability for day-to-day activities while still offering belly support.
Fit varies by torso height: If you have a longer torso, the waistband may feel more comfortable on the higher side of your bump; if you’re shorter in the torso, the waistband might sit slightly lower but still provide belly support.

Size Recommendations (by needs and body type)

For 24 weeks with a ~100 cm bump and sciatic discomfort: start with the maternity size that corresponds to your pre-pregnancy size. If you’re between two sizes, choose the larger for sit/stand ease and bending without restriction.
If you carry a higher bump and feel the waistband pinching at the lower back or hips: opt for the next size up and look for a wide, soft waistband that doesn’t roll.
If you’re tall or have longer legs: the 7/8 length is designed to hit above the ankle for most, but if you’re taller, you may notice the leg feels slightly short. In this case, a larger size can help the leg length settle, but verify the waistband comfort first.
If you’re petite or shorter in the torso: ensure the waistband sits comfortably higher and that the leg length doesn’t bunch around the ankle. A smaller size may line up better lengthwise if you don’t need extra belly space.

Size guidance at a glance (general):

Pre-pregnancy size small → maternity small, or medium if you need more belly room
Pre-pregnancy size medium → maternity medium or large if you want extra belly support
Pre-pregnancy size large → maternity large or extra-large if you’re between sizes for comfort Note: Always prioritize the belly panel and waistband comfort over snugness elsewhere. The goal is stability and ease of movement, not compression-only performance.

Between Sizes: What to Do

If you’re between two sizes and your priority is comfort for long sits or lying down (sciatic relief), size up. A looser waistband that still stays in place is better for relief than a tight fit that digs in.
If you’re between sizes but anticipate more active days (short walks, errands), you might prefer the smaller size to keep the leggings from shifting during movement; test the waistband’s grip and leg comfort.
For wearing out and about, choose the size that provides belly support without gapping at the back of the waistband. A slightly looser fit around the thighs can improve comfort when walking but should not compromise the belly support.

Common Fit Issues (and how to avoid them)

Digging waistband: If the band digs into the lower back or sides, move up a size or choose a pair with a wider, softer waistband.
Rolling waistband: If the top edge rolls down when you sit, size up or look for a garment with a smoother, non-roll waistband.
Too-short length: If the leg ends sit higher on the ankle and feel restrictive, consider one size up for length, especially if you’re taller or prefer a looser leg.
Sheerness or seams digging in: This typically happens with very tight fits or low stretch. Ensure you’re in the correct maternity size or consider a different cut that emphasizes comfort over compression.

Quick Answer for Your Situation

At 24 weeks with a 100 cm bump, start with the maternity size that matches your pre-pregnancy size. If you’re in between sizes or want extra belly support for long days, size up. For sciatic comfort, prioritize a high, soft waistband and ample belly panel so you can sit, lie down, or stand with less pain. Since you’ll be wearing these out of the house, choose a size that stays put during movement and doesn’t pinch or roll at the waist.

How to Measure for Best Fit (simple steps)

Bump and waist fit: Use your natural waistline and measure around your abdomen at the level where the belly panel sits. If you’re between sizes, prefer the size that gives you comfortable belly coverage without digging.
Hip area: Measure around the fullest part of your hips to ensure the leg portion isn’t too tight. If you have a wider hip line, lean toward the larger option.
Height and leg length: Consider your height relative to the 7/8 cut. If you’re taller, a larger size can help the leg length settle better and reduce ride-up.

Final Note from Our Team

Your comfort and daily usability come first. The 7/8 Body Shapewear Leggings with pockets are designed to provide belly support while staying comfortable for all-day wear, including long sitting periods. If you’re still unsure after checking the size chart, starting with the larger maternity size is a safe move for sciatic relief and practical out-of-house use.
