Frequently asked questions.
Everything about the technology, sizing, care, shipping and returns, in plain language.
The basics
What is undun?
undun makes elevated everyday tees with real bra-level support engineered directly into the garment. You get lift, shape, smoothing and coverage with no wires, no straps, and no separate bra, and it feels like you're wearing nothing.
How is undun different from a built-in bra or shelf bra?
Most "built-in" tops are a thin strip of elastic that offers almost no support and are made for casual wear only. undun uses patent pending construction that delivers the lift, shape and coverage of a real underwire bra, in a tee polished enough for work or a date.
Who is undun for?
Women who want real support and a flattering shape without the discomfort of a bra. Our volume-based sizing is built for a wide range of bodies.
Why does undun cost more than a basic tee?
You're not buying a T-shirt, you're replacing a bra and a top in one. The support system is a patent pending, engineered construction developed over dozens of prototypes by leading bra experts.
Sizing & fit
How does undun sizing work?
We use volume-based sizing instead of traditional cup-and-band math. Most women don't know their accurate bra size, so we built a quick sizing quiz that matches you to the right volume and size, no tape measure required.
What's the difference between Light and Medium Volume?
Light Volume is designed for roughly grapefruit-size and smaller; Medium Volume for roughly cantaloupe-size and larger. Both deliver shape, smoothing, lift and coverage, the difference is the amount of volume they're engineered to support. Take the sizing quiz for your best match.
What if it doesn't fit?

Care
How do I wash and dry it?
High standards, low maintenance. Machine wash, tumble dry. No hand-washing, no hang-drying, no special treatment.
Will the support wear out in the wash?
No. The support is engineered into the garment's construction, not glued-in pads or removable cups, so it holds up wash after wash.
