How to measure. Measure around the narrowest part of your torso, a couple of inches above your belly button, keeping the tape level. If you're postpartum, measure above the fullest part of your belly, not across it.

  • Sizing tip. Go by your waist measurement, not your usual clothing size. After a baby the two often stop matching. Between two sizes? We recommend sizing up for the most comfortable fit.

  • Fabric. A sculpting, four-way-stretch seamless fabric that adapts to your shape, supportive without ever feeling too tight.

  • 30-day money-back guarantee. If it isn't right for you, contact us within 30 days to arrange a return and get your money back. See our return policy for the full terms.

LUMIVE shaping underwear designed for everyday confidence

UNDERSTAND THE SUPPORT

Your middle deserves all-round support

Some days, you want a little extra hold around your lower belly. A comfortable, smooth fit starts with support that works with your whole middle.

The cross-band of LUMIVEā„¢ Underbelly Premium Shape-Underwear wraps the front, sides and back. Its smart-knit structure distributes the hold instead of concentrating it in one spot, helping your middle look smoother while you wear it.

  • 360° hold around the front, sides and back
  • Smooths and supports from the moment you put it on
  • A high waist designed to stay comfortably in place

Everything you want to know

How does the Underbelly Premium Shape-Underwear work?

The knitted cross-band runs around your belly, sides and back. Together with the high waist, it provides all-round hold to smooth and support your middle while you wear it.

When will I see a difference?

The shaping effect begins when you put the underwear on: your middle looks smoother and feels more supported under your clothes. This effect lasts while you wear it.

How often can I wear it?

It is designed for everyday wear. Choose a comfortable fit and wear it as part of your usual wardrobe. Take it off if you feel discomfort.

Can I wear it after pregnancy or a C-section?

Check with your healthcare provider before wearing shaping underwear after childbirth or surgery, especially if you have a healing incision. Only wear it once your provider confirms it is suitable for you, and stop if you feel pain or pressure.

Can I wear it while breastfeeding?

The high waist sits below the bust and does not cover your nursing bra. Choose a comfortable size and ask your healthcare provider if you have any concerns after childbirth.

Will it roll down or show under clothes?

The high waist and cross-band are designed to help the underwear stay in place. Seamless edges create a discreet fit under jeans, dresses and leggings. Choosing the right size helps you get the most comfortable fit.

Which size should I choose?

Start with the “Find your fit” guidance beside the product options and measure around the narrowest part of your waist. Between sizes? Choose the larger size. Contact us for sizing help, or within 30 days to arrange a return and refund if the fit isn't right.

How do I care for my shaping underwear?

Machine wash cold on a gentle cycle, preferably in a mesh bag, and dry flat. Avoid fabric softener, bleach and tumble drying to protect the fabric’s elasticity. Always follow the care label.

How do 30-day returns and refunds work?

Try your LUMIVEā„¢ Underbelly Premium Shape-Underwear in everyday life. If you are not satisfied, contact us within 30 days with your order number to arrange a return and refund. See our return policy for the full terms.
