Adjustable maternity jeans: A guide to maternity wardrobes

Can't button up your favorite pair of jeans anymore? Welcome to the world of maternity jeans! This piece will become your best friend for the coming months—and long after that, if you choose the right style.

At 23 Mai Paris, we support moms with a philosophy of a versatile wardrobe: clothes that take you through every stage of motherhood. This guide will help you choose a pair of jeans that will serve you well from pregnancy through the postpartum period.

When should you switch to maternity jeans?

That’s THE question every expectant mother asks herself. The answer varies from woman to woman, but here are the sure signs.

Signs that it's time:

• You can no longer button up your usual pair of jeans
• You're using the rubber band trick in the buttonhole
• Do you have a stomachache after wearing your regular jeans?
• You can only fit into your leggings anymore
• You always unbutton your pants when you're sitting down

The perfect timing:

Our advice: Don't wait too long! The sooner you buy, the longer you'll enjoy the benefits of your investment.

The 3 key elements of the perfect pair of maternity jeans

1. The belt: the heart of the system

This is what sets true maternity jeans apart from regular jeans. There are two main options:

Over-bump belt (high-rise waistband)

Under-bump belt (low-rise band)

The secret behind hybrid styles: Some jeans feature a waistband that folds over, allowing you to switch between under-bump and over-bump styles depending on your preference and stage of pregnancy.

2. Materials: elasticity for comfort

The fabric composition determines whether your jeans will keep you comfortable or let you down along the way.

The magic formula:

What to avoid:

• Less than 2% spandex → not stretchy enough
• More than 8% spandex → risk of rapid loss of shape
• 100% cotton → too stiff to conform

3. The cut: flatter your changing figure

Your body changes, so your jeans should too.

How to choose the right size?

Sizing for maternity jeans often confuses expectant mothers.

The golden rule: stick to your pre-pregnancy size.

Specialty brands are already anticipating changes in the hip and thigh areas. The waistband, meanwhile, is designed to stretch.

Before pregnancy → During → After

A good pair of maternity jeans isn't just for six months. They'll be with you:

• During pregnancy (6–7 months of use)
• In the maternity ward (postpartum care)
• The first few weeks after childbirth (it takes time for the body to recover)
• Sometimes several months later (especially with under-bump styles)

Why not put your jeans away right after giving birth?

• Your stomach won't go back to being flat right away (that's normal!)
• After a C-section, any pressure on the incision is uncomfortable
• The body needs time to stabilize
• The headband's comfort is a welcome relief during recovery

Pair your jeans with nursing tops

The harmony between the lower and upper sections creates an elegant visual continuity.

Winning combinations:

The headband trick:

With over-bump jeans, the waistband covers your belly even when you lift your top to breastfeed. That’s a significant advantage when it comes to discretion!

How much should you spend on maternity jeans?

The budget depends on your priorities and how long you plan to use it.

Our philosophy at 23 Mai Paris

Invest in ONE good pair of jeans rather than three mediocre ones. It’s a piece of clothing you’ll wear almost every day for at least 6–9 months. When you break it down by cost per use, even a pair of jeans that costs €80 works out to less than 50 cents a day.
