Washing a bamboo viscose bra so it keeps its shape
Short answer: Wash the bra according to the care label, use a low temperature and a laundry bag, and let it air dry flat. These are the three most important habits for a bamboo viscose bra to keep its shape. Here are the remaining steps and what to avoid.
Start with the care label
Every bra is different, and the care label is your safest starting point. It tells you the temperature and the programme that suit that particular piece. If you follow it, you have the best chance that the fabric, the elastic and the cups keep their shape for a long time, so you can wear the bra many times.
Use a laundry bag
A laundry bag protects the bra from catching on other clothes, and it stops straps and hooks from tangling in the wash. Close the hooks before you put the bra in the bag, so they do not catch on the fabric. It is a small thing that makes a big difference for a bamboo viscose bra.
Low temperature and a gentle programme
High heat can make the elastic slack and the fabric less pleasant, so choose a low temperature and a gentle programme. That also goes for bamboo bra without underwire, where the band and cups should keep their shape. It is best to wash the bra with clothes of the same colour and similar light fabrics.
Mild detergent and no fabric softener
A mild detergent is usually the best choice for delicate clothes. Use no more than you need, so no residue stays in the fabric. Fabric softener can leave a film on the fibres and make the elastic less stretchy, so many people leave it out when they wash underwear.
Do not wring or twist
If you want to remove water after washing, press the bra gently rather than wringing it. Wringing pulls at the fibres and can distort the bra. If you wash by hand, rinse well and press the fabric softly into a towel, then leave it lying flat or hanging so the shape is kept.
Dry it flat or hanging
The tumble dryer and strong heat are a bra's worst enemies, because they stress both fabric and elastic. Let it air dry instead, either lying flat on a towel or hanging on a drying rack. Hang it by the whole band rather than from a single point, so you do not pull it out of shape.
Rotate between several bras
A bra lasts longer if it is not worn every day. Give the elastic time to recover between wears, and rotate between several so each one gets a rest. That also means you do not need to wash it as often, and the shape holds better over time.
Store it so the cups are not squashed
Once the bra is dry it belongs in the drawer without being pressed together. Do not fold the cups into each other, especially if they are moulded. Keep it with the rest of your underwear, for example bamboo panties, and take out a bamboo T-shirt for women when you repack.
Frequently asked questions
Can a bamboo viscose bra go in the tumble dryer?
It is usually not recommended, because heat can affect the fabric and the elastic. Check the care label, and let the bra air dry if you want to keep its shape as long as possible.
How often should I wash my bra?
It depends on use and season, but many people wash it after a few wears. Rotate between several bras so each one has time to recover between washes.
Why does the bra lose its shape?
It is often caused by high heat, the tumble dryer or wringing, and by wearing the bra too often without breaks. Follow the care label and use a bag to protect the shape.
