Wedding Dress Slips: What They Do and When You Need One

When you're shopping for your dream dress, it’s easy to focus on the exterior—the lace, the train, the fit. But what’s underneath matters, too. Wedding dress slips may not be the most glamorous part of your bridal look, but they can completely transform how your gown looks and feels on your big day.

Whether you're aiming for extra volume, a smoother silhouette, or all-day comfort, a slip could be your secret weapon.

What Is a Wedding Dress Slip?

A wedding dress slip—also known as an underskirt or petticoat—is a structured or soft piece of undergarment worn beneath your dress to help it:

• Keep its shape

• Add volume where needed

• Prevent cling or transparency

• Make walking and dancing easier

Depending on your gown’s style and fabric, a slip can make a subtle but important difference.

Do All Dresses Need a Slip?

Not always. Some gowns are designed with built-in structure, lining, or layers that make a slip unnecessary. But in many cases, a well-chosen slip enhances the dress dramatically.

You should consider a slip if:

• Your dress feels too flat or doesn’t hold its intended shape

• The fabric clings awkwardly or shows underwear lines

• You're wearing lightweight or unlined materials

• You want to lift the hem slightly for better movement

• You’re adding extra support for a long day on your feet

Types of Slips for Wedding Dresses

There’s no one-size-fits-all. The right slip depends on your dress shape and how much structure or volume you want.

Here are the most common types:

1. A-Line Slips

• Adds subtle volume from the waist down

• Perfect for classic A-line and ballgown dresses

2. Ballgown Petticoats

• Max volume for dramatic skirts

• Often made with tulle and multiple hoops

3. Mermaid and Trumpet Slips

• Fitted through the thighs with flare at the hem

• Helps maintain the signature shape of these styles

4. Slips with Hoops

• Keeps heavy skirts lifted off the legs

• Adds air circulation and easier movement

5. Shapewear Slips

• Smooths the silhouette without adding volume

• Great for sheath, column, or fitted gowns

Choosing the Right Slip

Here are a few tips for getting it right:

• Match the dress shape: Don’t try to force a full ballgown petticoat under a mermaid dress. It will distort the shape.

• Try it on with your gown: Bring your slip to your fittings to ensure compatibility.

• Prioritize comfort: You’ll be wearing it for hours. Make sure you can sit, dance, and breathe easily.

• Adjust hem length: A slip can slightly lift your dress, so factor it in before final alterations.

Where to Buy or Find a Slip

Slips are often available at bridal salons or online retailers, but if you're purchasing a pre-owned gown, ask the seller if a slip is included or recommended.

At Kleinfeld Again, many of our listings include detailed notes on whether a slip was worn or needed. You can also message sellers to ask what worked best for their dress.

The Bottom Line

A wedding dress slip may not get much attention, but it can be the hidden hero that helps your gown shine. From creating elegant volume to ensuring a smoother, more flattering fit, the right slip makes a major difference in your overall look and comfort.
