For reference: I am 5’5”, 220 lb, and wear around a 16-20 depending on the brand. I ordered this corset in both a 4X and a 3X. The 4X laced up all the way with some room to spare at the top border and the 3X fits perfectly with some small space left in the back lacing. I am so in love with the shape of this corset. It provides excellent support, tucks in right at my natural waist, has wonderful coverage at the top back where I’d normally have spillage over the corset and the bottom covers my hips and apron belly beautifully. I’ll admit it’s not the most comfortable to sit in (but I challenge anyone to find a corset that is comfy to sit in) but I barely notice it standing up, even fully laced. It offers a beautiful dramatic hourglass shape and I don’t feel squashed or overflowing in any way. I use many corsets in costuming and can confidently say I’d repurchase this corset many times over. My only complaint if you can call it that is that I do not believe the boning beyond the front and rear busks are actually spiral steel, they feel a lot flimsier than other spiral steel corsets I own. If it is, then great, but my point still stands that the integrity feels less sturdy than others I’ve tried. That said, this still is one of my favorite cuts by far and the lack of boning integrity would not stop me from repurchasing this corset.

ABOUT OUR CORSETS

At Corsets Island, we offer a wide range of corsets designed to complement your unique style and body type. Our corsets are carefully crafted using high- quality materials to ensure they are both comfortable and durable.

SIZING

If your natural waist is 30 inches, select a M (30") corset for waist training, as it will close down to 26 inches, giving you a 4-inch reduction. For costume or cosplay, we recommend buying one size up for a more comfortable fit without the full waist reduction
