Big Skirt Energy: Bubble Hems, Tulip and Puffball Shapes Explained
After years of slip skirts and straight columns, 2026 has rediscovered volume. “Big skirt energy” is the shorthand for a whole family of rounded, sculptural shapes turning up on the high street — bubble hems, tulip skirts and full puffball styles. They look intimidating on the hanger and wonderful on. Here’s what each one actually is, and how to wear it.
The three shapes, decoded
- Bubble hem — the fabric curves back under itself at the hemline, creating a soft, rounded finish. It’s the most wearable of the three and works on skirts and dresses alike.
- Tulip — panels of fabric overlap and taper toward the hem like the petals of a flower. Neater than a puffball, with a gentle curve rather than full volume.
- Puffball — the boldest: gathered, voluminous and rounded all the way round. A statement piece rather than an everyday one.
The golden rule: balance the volume
A big skirt needs a neat top. This is non-negotiable. Pair any of these shapes with:
- A fitted knit or vest
- A tucked-in shirt
- A slim long-sleeve top
Keeping the upper half close to the body stops the outfit from overwhelming you and lets the skirt do the talking.
Shoes and proportion
Because the volume sits at the hip and hem, footwear helps re-lengthen the leg. A pointed flat or a heeled mule works better than a chunky boot with a shorter puffball. If the skirt is on the fuller side, a little height keeps the proportions elegant.
Who they suit (everyone, actually)
The myth is that volume only works on the very slim. It isn’t true. A bubble hem skimming at the narrowest point of the leg is genuinely flattering on most shapes — the trick is choosing the right length. Midi lengths that end mid-calf are the most universally flattering; very short puffballs are the trickiest.
Start with a bubble-hem midi if you’re new to the trend — it’s the gateway shape. Once you’ve seen how a bit of volume can look both playful and polished, the tulip and puffball won’t feel nearly so daunting.
