Myth, white underwear shows least under light clothes

Short answer: White underwear shows most clearly under light clothing. Contrast with the skin decides how visible it is, and white sits furthest from skin tone. A shade close to your own skin is the most discreet choice.

Contrast with the skin decides it

When you look at light clothing, you see not only the fabric but also what lies beneath. A layer in your skin tone blends with the skin and disappears. White stands out because it is far from most skin tones, so it shows through. The bigger the difference, the more visible it is. See the women's range.

White reflects light

Under a thin, light fabric, white underwear reflects light back and stands out clearly. The skin around it reflects less, so the edge and shape of the underwear become visible. This is especially true in daylight and bright lighting. See bamboo sweatshirts for women, where a fuller fabric covers more than a thin top.

Find your own skin tone

Skin tones vary, so no single colour suits everyone. Hold a piece of underwear against the inside of your arm and see whether the colour blends in or stands out. The shade closest to your own skin is the one that shows least. It may be lighter or darker than you expect.

Fabric thickness plays a part

The thinner and more see through the outer fabric is, the more the colour underneath matters. Under a thick sweatshirt, hardly any colour shows through. Under a thin blouse or a white T-shirt the difference becomes clear. Hold the garment up to the light to see how much it hides.

Edges and seams can show too

It is not only colour that can give underwear away. Seams, edges and lace can show through thin fabric, especially when it fits close. Smooth underwear without marked edges is less visible under fitted clothing. So think about both colour and shape when choosing what to wear under light clothes.

Under dark clothing it is the other way round

Under black, black underwear is the least visible choice. Here the contrast with the dark fabric is what counts, and a dark shade disappears into it. White or light underwear can show through thin dark fabric just as white shows under light clothes. See bamboo sweatwear.

A small set that covers everything

You do not need many colours. One set in your skin tone for light clothes and one in black or a dark colour for dark clothes covers most situations. White still works under thick clothing or on days when it does not matter if it shows. That way you always have a suitable choice.

The conclusion

The myth that white shows least under light clothing does not hold. Contrast with the skin decides it, and white sits furthest from skin tone. Choose a shade close to your own skin under light clothes and a dark colour under dark clothes.
