At Shapellx.com, sizing is designed around real body measurements. This guide will walk you through:

• How to properly measure yourself

• How sizing differs across product types

Why Accurate Sizing Matters in Shapewear

Unlike regular clothing, shapewear is designed to:

• Provide structured compression

• Support natural curves

• Smooth the body without restricting movement

Because of this, sizing based on your “usual dress size” or weight often leads to discomfort or poor shaping results.

The key to selecting the correct SX size is simple:

Always use your actual Bust, Waist, and Hip measurements.

Step 1: How to Measure Yourself Correctly

Before checking the size chart, you need accurate numbers.

What You’ll Need:

• A soft measuring tape

• Light clothing or fitted undergarments

• A relaxed standing posture

Important tips:

• Stand upright with feet shoulder-width apart

• Do not suck in your stomach

• Keep the measuring tape snug but not tight

• Ensure the tape stays level around your body

1️⃣ Bust Measurement

• Wrap the tape around the fullest part of your bust

• Keep the tape parallel to the floor

• Breathe naturally

If you’re selecting a bodysuit or shaping bra, this measurement is especially important.

2️⃣ Waist Measurement

• Measure around the narrowest part of your waist

• Stay relaxed — don’t pull the tape too tight

The waist measurement plays the biggest role in determining abdominal compression and shaping strength.

3️⃣ Hip Measurement

• Measure around the fullest part of your hips

• Keep the tape level and comfortable

This measurement ensures smooth fit in shorts, briefs, and bodysuits.

Step 2: How to Use the Official SX Size Chart

Shapellx sizing is structured around measurement ranges for:

• Bust

• Waist

• Hips

Available sizes typically range from:

XS – S – M – L – XL – 2XL – 3XL – 4XL

Each size corresponds to specific measurement intervals.

Scenario A: All Measurements Fall Within One Size Range

This is the easiest case.

If your bust, waist, and hips all fall into the same size category, choose that size confidently.

Scenario B: Your Measurements Fall Into Different Size Categories

Example:

• Waist fits M

• Hips are closer to L

In this case, prioritize based on your shaping goal:

For bodysuits, never compromise too much on bust or hip room — compression should shape, not restrict.

Scenario C: You’re Between Two Sizes

This is very common.

Here’s the general guideline:

• For firmer shaping → Choose the smaller size (if within range)

• For all-day comfort → Choose the larger size

Important rule:

Never choose a size below your measurement range just to increase compression.

Overly tight shapewear can cause:

• Restricted breathing

• Rolling edges

• Visible bulging

• Discomfort during long wear
