Bamboo strappy tops and when they work as a layer

Short answer: A strappy top is the thinnest layer you can put under other clothes. It adds nothing over the shoulder, so it does not change how your shirt or cardigan sits.

Why a thin layer is useful

A layer under a shirt takes moisture and friction away from the skin, so the outer garment stays fresh for longer. It just should not be seen or felt. The strappy top does that, because it covers the chest and back without adding anything at the shoulders, where the fit of a shirt is decided.

Under a shirt or cardigan

Because the straps are thin, there is no extra bulk at the shoulder. A shirt sits as it should, and the shoulder seam falls in the right place. Wide straps, by contrast, push the shoulder of the shirt out of position, which shows most on thin, close fitting shirts. See bamboo tops for women.

On its own in the heat

If the top is worn alone, the fabric needs to be heavy enough not to be see through. Hold a hand behind the fabric in daylight. If you can see the outline of your hand, the top works better as a layer. If the fabric is dense enough, it is a light and calm choice on warm days.

The problem with slipping straps

Straps that sit far out on the shoulder slip. A model with straps closer to the neck stays put, even when you carry a bag or reach for something. If the straps can be adjusted, tighten them a little, but not so much that they dig into the shoulder.

Under a dress

A long strappy top can do the same job as a slip under a dress that is slightly see through or clings to the body. It creates a gliding layer, so the dress falls freely. If the dress is short, the top just needs to be long enough. See bamboo slips and bamboo dresses.

Colour under light shirts

Under a white or light shirt, a white top often shows more than a skin toned one, because the contrast against the skin shines through. Choose a colour close to your skin tone under light shirts, and save strong colours for days when the top is worn alone or under a dark cardigan.

Length under the shirt

The top should be long enough to stay tucked in when you reach up. Otherwise it creeps up and forms a ridge under the shirt. A slightly longer model is therefore the best choice as a layer, even though it is not meant to show.

Washing and care

Wash the top at 40 degrees and skip fabric softener, which coats the fabric and makes it worse at moving moisture. Hang it to dry or use the tumble dryer on low heat. That way the straps keep their shape and do not shift after a few washes.

In short

A strappy top is the layer that adds the least. Wear it under shirts and cardigans where the shoulder needs to sit right, and wear it alone only if the fabric is dense enough. Choose straps close to the neck and a length that stays tucked in.
