A modern evolution of vintage shaping, our Demi Waspie Corset delivers the perfect balance of control, comfort, and curve. Designed as a stretch underbust corset for easy everyday wear, it sculpts your waist with the elegance of classic corsetry while allowing you to move freely from morning to midnight.

Combining the best of both worlds, this ingenious design pairs the structure of traditional steel boning with the gentle flexibility of powermesh. The result is a smooth, defined silhouette that enhances your natural shape without the rigidity of a full corset. A satin centre panel adds a touch of glamour, while the double-layer powermesh body hugs comfortably against the skin.

To accentuate the waist, a double elastic waist tape offers extra cinch where it counts, creating a striking yet wearable hourglass shape. Lacing at the back allows you to adjust the fit precisely to your comfort level — simply open wide, step in, and tighten to your liking.

Don’t be fooled by its softness: with 12 spiral steel bones and 6 flat bones, the Demi Waspie provides reliable structure and gentle support beneath both vintage and modern clothing.

Made ethically in our Indian atelier, this corset is crafted from quality materials for a long, beautiful life — proof that true glamour can be both kind and comfortable.

For those who adore an elegant waistline without the formality of full corsetry, the Demi Waspie Corset is a revelation — effortless shaping for the modern vintage silhouette.

Wore this to an event and it was perfect for what

Wore this to an event as someone who had put on a lot of weight recently and it was perfect for what I needed, gave me a lovely shape, smoothed lines and snatched me in at the waist.

As a bonus it was very comfortable and supported my lower back making me stand and sit straighter without feeling restrictive. I was worried the ribbing would dig into my thighs sitting down or constrict my breathing and dig in but it sat well on me being firm enough to hold me in and flexible where it might otherwise dig in.

I only wish it was as easy to get on and off like one with a busk opening, but I understand why as it is smoothing at the front and is flexible to sit in.

Gorgeous!

This is beautifully made and such a lovely colour (I got peach). Soft comfortable material, strong long lacing to fit many body types. No pulling at the seams, boning molds to frame nicely, very comfortable. A bit harder to stealth under tighter thin clothing but easy otherwise. Great back support and very easy to breathe in. Great fit and quality, worth the price.
Very happy with this purchase, thank you Katie!

Give yourself an hourglass figure in a cinch

This Demi Waspie Corset is exquisite and definitely worth adding to your collection. Top to bottom the Maitresse collection is every boys pin-up dreams come to life, the finish on this corset is so beautiful. They could have painted my wife wearing this collection on the nose of a B-24 and kamikaze pilots would have been crashing into each other instead.

Fits true to size

Amazing, but should definitely come with instructions!

Context: I was looking for shapewear for regular use under my clothes that emulated what I came to discover is the "waspie" silhouette. After a visit to the Dior museum here in Paris, I really wanted to find shapewear that could give me a similar shape to some of the garments I saw. I have no prior experience with corsets.

The demi waspie corset is really good quality. It feels sturdy and the material is really comfortable! It understood the assignment and snatched the **** out of my waist. It gives me an absolutely stunning silhouette. Getting it on the first time took a good 30minutes, and as a first time corset wearer I had no idea what I was doing. The second time I decided to follow a tutorial and that helped immensely. So I would recommend doing that. The laces are so long and it doesn't seem to be tied in exactly the same way as a traditional corset so it would be really cool if the "What Katie Did" team added a tutorial for how to wear and lace up this particular garment as it's pretty unique.

It's super comfortable, can definitely be worn all day if you wanted to

I've not figured out how to perfectly cover my lines for when I wear it underneath clothing or the best way to tuck all that lacing but I am sure in due time I'll figure it out. If you're thinking about getting it, don't hesitate!

From black to peach

Having bought last year this fabulous all-day shapewear in black, I decided to splash out on peach. So comfortable. So wearable. So delectable. And it really does do the trick with my waist.

Amazing

I love this piece. I've been wearing it after having my second child. It is surprisingly comfortable to move in. I wear it twice as much as I thought I would! It olds in all my squish and lets me wear my old clothes.

You have to wear it to believe it

This is the most comfortable corset I have ever worn. It's very light and delicate but still reduces my waist noticeably. It is mentioned in the product description that there is no busk and the laces are longer than usual, so you will need more time to put it on. It does not bother me personally though, and the busk-less front is invisible under lighter clothing. I can't wait to wear this beauty in spring and summer. Thanks, WKD!

Very happy with it. Exactly what I had hoped for. So happy you are making larger sizes (I bought the 22).

Given the lacing, eyes and bow, what clothing would you be able to wear this corset with for it to be unnoticeable? How thick should the fabric be, should it not contain certain materials, etc.?

What Katie Did

Hi there,

Thank you for reaching out!

I'm afraid it is a little bit trial and error to see which fabrics work best. As a general rule of thumb any silky/satiny/slinky dresses most likely won't work as they would cling to the corset and the laces would likely show through.

I'd say most fit and flare styles should work nicely, you can easily tuck excess laces under your corset to keep them out the way. Additionally, if you wrap the laces around you before trying this will help reduce the bulkiness of the knot/bow.

I hope this helps somewhat!

Kind Regards,

Charlie

Is it possible to wear for work? To move around without being restrictive?

What Katie Did

Thank you for reaching out!

Our Demi corsets are a great option for daily wear as they are made with power mesh fabric which allows them to be more flexible.

They are made with steel boning like our other corsets, so they will still provide a lovely cinch.

Please do let us know if you require any sizing advice and I will be happy to help.

Kind Regards,

Charlie
