Ladies, meet our best selling long sleeve backless Siren catsuit. There was no other name for it; everyone who has worn this sassy spandex specimen has turned heads wherever she goes.

    The long sleeves are made out of black glitter mist to give them a slightly opaque, sparkly look and the quality spandex supports and pulls in where needed. The body of the catsuit features a subtle snakeskin shine, giving it a whole other level of glamour and edge.

    The Siren is the must have for any party girls' wardrobe and is a go-to fail-safe for festivals, parties and really - any occasion that calls for some lycra. It also makes for a killer Halloween costume!

    Using contrasting fabrics and pattern cutting techniques, we’ve created a backless catsuit that not only offers support but contours the figure to make you feel and look like a billion dollars whenever you put it on.

    • With every catsuit, you’ll receive complementary nipple stickers to keep a smooth appearance at all times

    • The incredible glow from our reflective hip panels come from a coating of tiny glass beads in adhesive which is fused to the fabric and due to this they need to be treated with care. We don’t advise them to be worn with anything that can act like sandpaper to the coating... for instance a bumbag with a rough backing like sequins of cracked leather.

    Hand wash your Lycra outfit in cool or tepid water using mild detergent. 

    Drip dry away from direct heat and sunlight and 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 - 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. Drip dry 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!

    I ordered two outfits this being one and didn’t end up sending either back! ❤️✨❤️

    Amazing Cat suit A* defo a must buy for curvy girls

    Ive never worn an item like this before and was so thrilled when it arrived. Prior to ordering i messaged the Burnt soul team as im smaller on top (8-10) and bigger on bottom (10-12). I have a tiny back too and big boobs so I wasn't sure what size to order because of this and ive not been able to wear Cats suits or jump suits because of my curvy shape. The lovely ladies there gave me some great advice a recommended a medium. Ive brought this Catsuit to wear at a rave next month. When i tried it on I couldn't believe how much it complimented my shape. It nips you in on the waist, thighs and I think its even lifted my bottom. I felt so confident and also like I could audition a Mystique from Xmen as its so cool ahah :-). Its been really well made and is great value for money. I honestly cannot wait to upload my pic with my dressed up in it on the insta page when I where it in November... These Catsuits are simply the best, I cant wait to buy more


    This is one snazzy outfit, as soon as I put it on I felt amazing. The fit was great on the body I’m pretty short so the sleeves and legs are a tiny bit long, but I have a handy mum who has turned them up and now it’s perfect!!

    If only I had an infinite pool of money for catsuits!

    I would buy one of every catsuit these gals have to offer, and would buy one for each of my friends as well!

    This super flattering piece feels like the second skin I never knew I was looking for (until I put it on, of course).

    If you have been eyeballing one of these for a while, go ahead and pull the trigger. You won't be sorry!

    Incredible Performance-wear

    I wore my new catsuit on stage with my band Ace of Wands for the first time last night and loved it!! So comfortable and breathable, and made me feel like a superhero of music. Thank you!!
