The best bamboo under shorts for women and what they need to do

Short answer: Undershorts should stay where they are when you walk. That takes a leg edge that grips no tighter than the rest, and a leg long enough to cover the inner thigh so skin does not rub against skin.

Leg length is the whole point

Undershorts that are too short ride up and cause exactly what they were meant to prevent. The leg must reach past the point where your thighs touch as you walk. Measure yourself before choosing, and go a few centimetres too long rather than too short. Browse bamboo undershorts.

The edge must not dig in

A wide, soft leg edge or a laser cut edge stays flat without showing through a dress. Narrow elastics dig into the thigh and roll up. That one detail decides whether you wear them every day or leave them in the drawer. Feel the edge before you buy if you can.

The waistband must stay put

A waistband that rolls down or digs into the stomach makes undershorts uncomfortable all day. Look for a wide waistband that lies flat and spreads the pressure. A high waist often gives a smoother line under a dress and sits better when you sit down and stand up again.

Under a dress or a skirt

Under thin summer dresses, a thin pair in a skin tone is the most discreet. Under a heavier skirt, a firmer pair can give a smoother line. Think about which colour shows least through the fabric rather than what colour the dress is. Compare with bamboo shorts for women if you want something you can also wear on its own.

Why bamboo

Warmth and moisture build up between the thighs, especially in summer. Bamboo viscose is soft and absorbs moisture, so it feels less clammy than many synthetic materials. A thin fabric also means you do not notice an extra layer under your dress. That is a practical advantage on warm days when you walk a lot.

For cycling and long walks

For the bike, a firmer model with a longer leg is better, because a short leg rides up as you pedal. The same applies on long walks. Choose the longest leg you find comfortable and an edge that lies flat. This is where you notice the difference between a good and a poor model most.

Size

If undershorts are too small, they grip at the leg edge and ride up. If they are too big, the fabric folds and can rub. Start from your usual briefs size and go up if you are between two. They should fit closely, but without the edge leaving marks on your skin after a day.

Washing and care

Wash undershorts at 40 degrees and skip fabric softener, which makes the fabric less absorbent. Avoid high heat in the dryer, because heat wears the elastic in the edge and waistband. Hang them to dry where you can. They then keep both their shape and the soft edge that is the reason to choose them.

In short

Good undershorts have a leg that is long enough, an edge that does not dig in and a waistband that stays put. Choose thin and skin toned under thin dresses, firmer under skirts, and a longer leg for cycling and long walks. Wash gently and they keep their shape for longer.

Frequently asked questions

Why do my undershorts ride up?

Because the leg is too short or the edge grips too tightly. Choose a longer leg with a wide, soft edge that lies flat against the thigh and does not dig in.
