What Is a Belly Band? | Every Meaning Explained

A belly band is a flexible wraparound band worn around the midsection, most often used during pregnancy to extend clothing and support the belly.

The term “belly band” covers more ground than most people expect. Merriam-Webster defines “bellyband” simply as “a band around or across the belly,” which explains why the same word describes a maternity garment, a newborn navel protector, a horse’s girth, and even the paper strip around a new book. If you searched the term while pregnant, you almost certainly mean the flexible tube-style garment that stretches over your abdomen. That’s the use this guide focuses on, with the other meanings covered briefly so you know exactly what you’re looking at.

What a Pregnancy Belly Band Does

A maternity belly band is a stretchy, tube-shaped piece of fabric worn around your waist and belly. It serves two practical purposes: it extends the life of your pre-pregnancy pants by letting you leave them unbuttoned, and it covers the strip of exposed skin as your abdomen grows. Some women wear them over jeans, others under loose tops for light support.

These bands are sometimes called belly sleeves or maternity bands. They differ from belly belts, which are rigid supports designed to brace the lower back, pelvis, and abdomen, and from postpartum wraps, which are firmer compression garments worn after delivery.

Other Things Called a Belly Band

The word appears in several unrelated contexts. Knowing these prevents confusion when you search for one and find another.

• Newborn navel protector: a soft band worn around a baby’s midsection to cover the healing umbilical stump.
• Paper packaging strip: the band of paper or cardstock around a book, magazine, or package, used as decoration or labeling.
• Horse tack girth: the strap that secures a saddle around a horse’s belly.
• Concealed-carry holster: an elastic wrap worn around the midsection to hold a handgun discreetly under clothing.

If your search relates to firearms, the belly band holster is a different product entirely from its maternity counterpart — though both share the “band around the belly” concept.

Choosing the Right Belly Band for You

Sizing a maternity belly band comes down to one measurement: your belly, not your pants. Use a flexible tape measure around the largest part of your stomach, typically at the belly button. Most bands are one-size or S/M/L ranges, so check the manufacturer’s size chart against this number before ordering.

For concealed carry, sizing works differently. Your band must fit snugly around your midsection without digging in, and you should pick a spot — low on the waistline, just above the belt, or around the solar plexus — where the gun stays hidden and accessible. Not every band fits every firearm, so confirm compatibility with your specific model before you buy. Some include a trigger shield that covers the trigger guard to help prevent accidental discharge.

The Bottom Line on Belly Bands

A belly band is any flexible band worn around or across the belly, but the meaning shifts with context. For pregnancy, it’s a stretchy garment that keeps your wardrobe working as you grow. For other uses, it’s a baby accessory, a book label, a saddle strap, or a holster. If you’re shopping, measure your belly, not your pants, and match the product type to your actual need.
