to tell fans about the trick, writing: "BRA HACK for square neck and sweetheart necklines!
"I find 99.9% of strapless bras annoying and uncomfortable so this is how I hack my favourite bras so they work in my shirred square-neck dresses.
"That way I still get the comfort and support but without the straps poking out."
In the accompanying video, Lottie took a hairband and looped it around the base of her bra strap - threading it through itself.
"Tighten, tuck and repeat," she said, doing just that.
Once Lottie had put the hairbands on each side, her bra straps were miraculously hidden from sight.
"Ta da!" she concluded as she showed off the finished look.
She was quickly praised by people in the comments section, with one writing: "Omg genius!"
"Seriously though. Where has this hack been all my life?!?!?!?! AMAZING," another person commented.
While a third added: "Best hack yet! Thank you for sharing this."
"You've just changed my life," someone else gushed.
