Leggings without lines from your knickers
Oct 11, 2026
Short answer: If you are looking for bamboo knickers for women to wear under leggings, choose a cut without wide elastic and with flat, soft edges. Fit and colour matter more than thickness, and the knickers should sit calmly without cutting in. That avoids most lines.
Why leggings show lines
Leggings sit close and in a single layer, so anything that presses under them becomes visible. It is mainly the leg edge and the waistband that show, and knickers in the right cut can reduce the problem. It is about edges and fit, not about you having done something wrong.
The right cut for leggings
Choose bamboo knickers with flat edges and a leg without wide elastic, for example a bikini or a tai. The most important thing is that the edge does not press into the skin, because the pressure makes the line. Very high-cut legs often sit where leggings stretch the most.
Size and fit
Knickers that are too small cut in and show a line, and ones that are too big fold up under the fabric. Try your normal size, and try two if you are unsure. Walk around a little in the leggings when you try them on, so you can feel whether the knickers stay in place.
The colour under leggings
Choose a colour close to your skin or to the leggings, and avoid pale knickers under thin, light leggings. Black leggings cover better than white ones, and thicker leggings show less than thin ones. Dark knickers under light leggings can show through, so always think about contrast.
Bamboo knickers for women under leggings
Bamboo knickers are made from viscose from bamboo, which is soft and adapts to the body. That means the fabric presses less hard and the edges become less visible. It is no guarantee, but it helps together with a good cut and the right size.
Washing and care
Wash as the care label says and use a laundry bag so the edges do not get pulled out of shape. Use a mild detergent and little fabric softener, and dry them flat. Knickers that have lost their shape often start to roll or fold, and that is exactly where lines appear.
If the lines still show
Then try another cut, one size up or down, or a different waistband. Also check whether the leggings themselves are too tight or too thin, because they can show everything. Sometimes switching to leggings in a thicker fabric helps more than switching knickers.
The rest of the outfit
Lines do not only come from knickers. A tight T-shirt can show an edge at the waist, and socks can make a line at the calf. Try bamboo T-shirts for women in a smooth cut and socks for women without a tight edge, so the whole outfit sits calmly.
Frequently asked questions
Which knickers do not show under leggings?
Knickers with flat edges, without wide elastic and in the right size show the least. A bikini or a tai is often a good place to start.
Should the knickers be the same colour as the leggings?
Not necessarily, but a colour close to your skin or to the leggings shows the least. Avoid pale knickers under thin, light leggings, where they can show through.
Is bamboo better for leggings?
Bamboo is soft and adapts to the body, so the edges press less. It is not decisive alone though, because the cut, size and thickness of the leggings matter just as much.
