A checklist for buying new underwear

Short answer: Before you buy new underwear, check size, fabric, seams, elastic and care. With five fixed questions you avoid the purchases that end up unused at the bottom of the drawer.

Question 1: What size are you actually now

Measure yourself instead of reaching for the size you usually take. Bodies change over the years, and sizes vary between brands. Put a tape measure around your hips and read the size chart for the specific product. If you fall between two sizes, think about whether the fabric has a lot of stretch. A soft knitted fabric gives a little, while a firmer fabric sits as it is. See bamboo panties for an overview of models.

Question 2: What is the fabric made of

Check the fibre content label. Cotton, viscose from bamboo and blends with elastane behave differently in wear and in the wash. Viscose from bamboo has a smooth, soft surface and often feels cooler on first touch. Elastane gives stretch and fit, but too much can make the fabric less breathable. Look for a blend that suits the use. For everyday wear, a soft fabric with a little stretch is usually the best choice.

Question 3: How are the seams and edges

Turn the underwear inside out and look at the seams. Flat seams chafe less than thick ones, especially under trousers or in a close-fitting dress. Check the edges at the legs and waist too. The elastic should lie flat and not dig into the skin. Stretch it gently and see whether it springs back. An edge that is already slack in the shop will not improve after a few washes.

Question 4: Does it suit the season and your day

Think about what you will be doing in them. For long days at the office or in the car, soft and smooth underwear is pleasant, while on cold days you may want an extra layer underneath. Tights are a good example, because they must both hold their shape and be comfortable all day. See bamboo tights for women if you want a layer under a dress or skirt in autumn and winter.

Question 5: How should it be cared for

Read the care label before you buy. Underwear often needs washing frequently, and it is nice if it can cope with 30 to 40 degrees without trouble. Avoid fabric softener, as it can leave a film on the fabric. Drying on a rack is gentler on the elastic than a tumble dryer. If you already have a wash bag, you protect seams and edges even better. If you want to refresh your bathroom linen at the same time, look at bamboo towels.

Question 6: How many pairs do you need

A simple rule of thumb is to have enough for a week plus a few spare for wash days. For most people that means seven to ten pairs. Buy a few of good quality rather than many in mixed condition. Once you have found a fit that works, you can buy several of the same model so the fit stays the same. Write down the size so you can find it again.

Frequently asked questions

How often should underwear be replaced

There is no fixed rule, but when the elastic is slack, the fabric thin or the seams chafe, it is time for new. Many people feel it themselves long before it can be seen.

Should new underwear be washed before first use

Yes, that is a good idea. It removes residues from production and transport, and the fabric often becomes a little softer.

Can I try underwear on before buying

It varies from shop to shop. Always check the terms for exchange and returns, so you know what applies if the size does not fit.
