The Victorias Secret Fashion Show is a tradition thats a bit tricky to explain.
Each year a bunch of very slim models get up on a runway wearing underwear and massive wings. Those very slim models have been carefully selected from a giant list of models who count the show as their dream gig, and are all extremely excited to be there.
One of those models wears an extra-special bit of underwear, called the Fantasy Bra.
The Fantasy Bra is, well, a bra. But its much posher than your standard bit of underwire.
The Fantasy Bra gets a redesign each year, but usually a few things are kept consistent: Its sparkly, its hugely expensive, and just one lucky Victorias Secret model gets to wear it on the runway.
This year that model is Elsa Hosk, who became a Victorias Secret angel in 2015 after walking the runway for the first time in 2011.
This years Fantasy Bra is, as expected, extremely sparkly and expensive. The bra holds over 2,100 jewels of more than 71 carats. It took over 930 hours to make and is valued at $1million (£765,765).
In terms of cut, its based on the Dream Angels bra, meaning it has a longline silhouette and an underwire, with the addition of more crossbody jewels.
Basically, we wouldnt recommend wearing it underneath any old T-shirt – and not just because it sounds heavy.
The bra is actually not as fancy as last years Fantasy Bra, worn by Lais Ribeiro, if youre interested in comparisons, or the Fantasy Bra from 2016, which had 9,000 gemstones and more than 450 carats of 18k gold.
The good news is that if you are keen on getting a sparkly bra, you dont need to have a spare million. Victorias Secret is releasing a more affordable bit of lingerie inspired by the Fantasy Bra on Thursday 29 November.
The similar bra is $250 (£191) and covered in Swarovski crystals. Its not quite as sparkly, but its still pretty impressive.
