Dance
Class, rehearsals, performances. UnderDance is cut to work beneath high-leg leotards and costumes without adding a standard brief line where nobody asked for one.
UnderDance™
For leotards, costumes and activewear.
Your leotard has a high leg. Your period undies got the memo.
UnderDance™ puts serious period protection into a high-cut brief designed to sit smoothly under dancewear, gymnastics leotards and activewear.
Shop UnderDance See the fit
Regular period undies can peek out below the leg line of a leotard or costume. Not exactly the look anyone was going for.
UnderDance sits higher on the hips, with a scooped front and cheekier Brazilian-style back so there’s less underwear where you don’t want to see it.
A soft, flat waistband and four-way-stretch microfibre keep things smooth while you bend, stretch, leap, tumble and generally refuse to stand still.
A short, silent fit demonstration. Press play when you’re ready.
No strategic camera angles. No crossed fingers. Watch UnderDance from the front, side and back as the leotard goes on, comes off and movement gets involved. Every leotard is cut differently, so check UnderDance with yours before performance day. Five minutes in the bedroom mirror beats finding out under stage lights.

Class, rehearsals, performances. UnderDance is cut to work beneath high-leg leotards and costumes without adding a standard brief line where nobody asked for one.

Built for high-cut leotards and bodies in motion. Bend, stretch, split, tumble. Check the fit with her competition leotard before the big day, because costumes enjoy having opinions of their own.

The high-cut shape also works under leggings, bike shorts and other activewear. Because UnderDance doesn’t actually check whether you’ve entered a studio before doing its job.

Training Tuesday. Rehearsal Thursday. Comp Saturday.
Periods rarely consult the timetable. Build an UnderDance rotation so there’s a clean pair ready when she needs one.

Match UnderDance to her flow and how long she’ll be wearing it. For long rehearsals, training days or competitions, pack a clean spare and somewhere to put the used pair.
Change when needed. There’s no prize for seeing how long one pair can go.
Rinse. Rinse after wear in lukewarm water until the water runs clear.
Wash. Cold machine wash with similar colours. Skip the fabric softener.
Air-dry. Line dry fully. No tumble dryer.
It’s designed with a high-cut shape specifically to work beneath higher leg lines. But leotards vary in cut, fabric, colour and fit. Try the two together and check front, sides and back while moving.
High and comfortable on the hips, with the back smoothed into place and the absorbent area sitting close to the body. It has a Brazilian-style cut with cheekier back coverage, not a full brief.
Measure her low hip first and check her waist second. If she falls between sizes, size up. Measurements beat age and usual clothing size every time.
Approximately 2–3 tampons or four regular pads. Treat that as a capacity guide rather than a number of guaranteed hours. Flow and changing opportunities vary.
No. The same high-cut shape works for gymnastics, acro and activewear whenever a lower-cut brief is likely to show.
UnderDance comes in Black, Neutral and Brown. Check the colour beneath her actual outfit in good light. There is no single “invisible” shade under every fabric or on every skin tone.
Rinse after wear, cold machine wash with similar colours and air-dry fully. Skip fabric softener and the tumble dryer.
