Butt & Hip Padding for Costumes

Choosing a Padding Material

Foam padding (upholstery foam or dance/costume-specific padding) is the most common choice because it's lightweight, easy to shape with scissors or a hot wire cutter, and holds its form well under fabric. Batting or fiberfill works for softer, less structured padding needs but tends to shift and compress unevenly over a long day, which can leave a costume looking noticeably different by evening than it did that morning.

Shaping for a Natural Silhouette

Layer padding in graduated pieces — a larger base layer with progressively smaller pieces built up on top — rather than one thick uniform block, which reads as noticeably artificial and can look boxy under fitted fabric. Taper the edges of each foam layer at an angle rather than cutting a hard vertical edge, since a hard edge is what most often gives padding away as padding under close-fitting costume fabric.

Securing Padding So It Doesn't Shift

Sew padding into a fitted undergarment (padded shorts or a built-in liner) rather than trying to tape it directly to skin for a full day — tape-based padding is more prone to shifting with movement and sitting. If the costume itself has a fitted lining, basting the padding directly to the lining at a few key points keeps it from migrating during wear while still allowing the costume's outer layer to move naturally.

Comfort Over a Full Convention Day

Padding that feels fine standing still in a fitting room can become genuinely uncomfortable after hours of sitting and walking, so test any padded piece through a full range of movement — sitting, walking, climbing stairs — before finalizing the build. Leave a small amount of breathing room in the fitted undergarment rather than pinning padding in place under maximum compression, which tends to cause both discomfort and visible shifting as the day goes on.
