Choosing the right size for maternity clothes can be confusing. Your body changes a lot during pregnancy. So, your clothes need to fit well and feel comfortable. But how do you know what size to pick? This guide will help you understand how to size maternity clothes easily.
Why Is Sizing Maternity Clothes Different?
Normal clothes are made for bodies that do not change much. But pregnant bodies change every week. Your belly grows, your hips get wider, and sometimes your bust changes. So, maternity clothes are made to stretch and fit your changing shape.
Because of this, maternity clothes often have stretchy parts or extra fabric. They may also have adjustable bands or panels. This helps the clothes fit during different pregnancy stages.
Know Your Pre-Pregnancy Size
First, know your size before you got pregnant. This size is a good base for maternity clothes. Most maternity clothes use your pre-pregnancy size as a guide. For example, if you wore size Medium before, you will likely wear a Medium in maternity clothes too.
But remember, maternity clothes are made to be roomier and stretchier. So, they will fit your growing belly better than normal clothes.
Take Your Measurements
Measuring your body is very helpful. You can do this with a tape measure. Here are the main places to measure:
- Bust: Measure around the fullest part of your chest.
- Waist: Measure around the smallest part of your waist.
- Hips: Measure around the widest part of your hips.
- Belly: Measure around your pregnant belly, if you are already showing.
Write down these numbers. They help you check the size charts of the clothes you want.
Use Size Charts
Each brand has a size chart. It tells you which measurements fit which size. Size charts are the best tool to find your maternity size. You can find them on store websites or on clothing tags.
Compare your measurements to the chart. Pick the size that matches your largest measurement. For example, if your hips are bigger than your bust, choose your size by your hips.
Consider the Stage of Pregnancy
Your size will change as your pregnancy grows. Early on, you might wear your normal size. But later, you will need bigger clothes. Some women buy maternity clothes for each trimester. Others buy clothes that fit well for most of pregnancy.
Think about how long you want to wear the clothes. If you want to wear them for many months, choose a size that can stretch or adjust.
Look for Adjustable Features
Maternity clothes often have special parts to adjust size. These can be:
- Elastic waistbands that stretch.
- Side panels with stretchy fabric.
- Drawstrings or buttons to tighten or loosen.
These features help clothes fit your body better as it changes. They also make clothes more comfortable.
Types of Maternity Clothes and Sizing Tips
Different clothes fit differently. Here are some tips for common maternity clothes:
| Clothing Type | Sizing Tips |
|---|---|
| Maternity Tops | Look for stretchy fabric or ruching on sides. Choose your pre-pregnancy size for early pregnancy. Pick one size larger if you want a loose fit. |
| Maternity Pants and Jeans | Check if they have elastic panels or adjustable waistbands. Pick size based on your hips and belly measurement. Some pants fit under the belly, others over it. |
| Maternity Dresses | Choose dresses with stretchy material or empire waist. Size by your bust or hips, depending on dress style. Dresses with an empire waist fit well over belly. |
| Underwear and Bras | Buy bras with adjustable bands and soft cups. Choose underwear with stretchy sides or maternity panels. Measure your bust and underbust regularly. |
Try Clothes On Before Buying
If you can, try maternity clothes on before you buy. Every brand fits a little different. Trying clothes helps you find what feels best. Pay attention to how clothes feel around your belly and hips. You want clothes that are snug but not tight.
Walk around and sit down in the clothes. Check if they stay in place and feel comfortable.
Shopping Online? Check Return Policies
Shopping online is easy but tricky for sizing. Always read size charts carefully. Compare your measurements before buying. Also, check the store’s return policy. This way, you can return or exchange clothes if the size is wrong.

When to Buy Maternity Clothes
Many women start buying maternity clothes when their normal clothes feel tight. This is often around the second or third month of pregnancy. But every body is different. Some buy earlier, others later.
If you want to save money, buy a few key pieces first. Buy more clothes as you need them. This way, you don’t spend too much at once.
