Printed/plain Lycra with no foil panels - 30 Degree machine wash and line dry

Foiled pieces - Hand wash in cool or tepid water using mild detergent. Remove excess water with a spin cycle in your washing machine and then line dry away from direct heat and sunlight. Do not dry clean or tumble dry

Tackle stains straight away by quickly soaking the stain in cold or tepid water and rub small amounts of mild detergent to the affected area, repeat as necessary. Do not use hot water as this can set the stain. 

To remove strong smells fill the sink with cold water, add a cup of baking soda and soak for no more than 1 hour. Then wash as above.


We recommend hanging your Burnt Soul’s up when they’re not out causing mischief, especially if they’re more delicate foiled pieces.

Do not fold and put in a draw when damp - this will cause damage to any foils and could transfer fabric dye to other garments.


We love using glittery, shiny and holographic fabrics… as much as I’m sure you love wearing them! They do tend to need a little more attention than your average pair of leggings though.

Whilst we always buy the highest quality of sparkles and foils we can find, if they are being worn and washed as an every day item of clothing then the foils may dull.

If you’re looking for longevity or to use for fitness then it’s best to go for catsuits without liquid foil paneling. If you'd like more help choosing the right one for you then send us a message here.

keep oily liquids away from the reflective panels. The reflective panels are made by coating the Lycra in minuscule glass beads. this makes it hard to get out oily substances once on the fabric. The good news is that it will have no effect on the reflective glow it gives out so you can continue shine bright where ever you go!

Love this


Tracy Ford (Eastbourne, GB)

My little girl lives & dreams rainbows, so was blown away to get this catsuit for her 5th birthday. It went straight on, along with a cape, & we hit the beach to show it off! Size is true to size, we bought 5-6 & it fits her perfectly. Great product, great company.

Really lovely - exceeded expectations

We first came across Burnt Soul at Glastonbury a few years ago and our daughter insisted we buy her a catsuit. She's worn it, used and abused it over the last couple of years and finally outgrown it. This replacement looks just as good quality and our daughter looks so cute in it. Love the catsuits, love the brand.

Delighted daughter!

My daughter got one of these for her 10th birthday and she is delighted with it! She put it in immediately and we watched the sunlight sparkle off it! When all the festivals are back up and running, she’ll be shining like the diamond she is!

LCD (Brighton, GB)
Absolutely fabulous

Love, love, love the catsuit. Bought as a birthday pressie for my daughter, so she hasn’t seen it yet, but she will also adore it. Beautifully made. Can’t wait for her to be able to wear it. Thank you!
