One word: I love it! Nothing to do with the corsets you can find in non-specialist shops. I'll definitely buy more.

Zoe Booker

Excellent quality, especially for the price! Got the white as requested.

The corset is well built and sturdy, the fabric isn’t cheap and it’s relatively comfortable as far as corsets go. The string to tighten is a bit long but that also makes it easy to tighten by yourself. Overall I was very happy with it!

Rebekah Perkins

This corset feels like the real deal. It feels like it truly has steel boning and the fabric is very thick. It is already laced upon arrival and the laces also feel durable. The wide modesty panel is nice as well. It also seems to have correct sizing. I went up one size and could've easily gone smaller.

Emily Prendergast

This is a real heavy duty steel boned corset. It’s sized perfectly. I love that it’s adjustable using the strings which are lace up the back. This is a true waist trainer and will take some time to get used to. I filled the size chart and it fits me great. It’s very supportive and comfortable once you get used to it. I’ve been able to tighten it more and more with each use.

the corset is incredible! it's so comfortable and i cannot stop wearing it!

A surprisingly well constructed corset for such a good price. Just a little underbust waist trainer, but I’ve worn a lot of costume corsets, and this one is quite comfortable and sturdy, and arrived laced correctly!

The corset is absolutely beautiful. I got a custom sizing since I wanted to fit me in a very specific way, and the owner was so kind to help me. They were clear and patient. Am absolute pleasure to have worked with. The quality of the corset? Outstanding, God, I'd even buy more LOL I definitely recommend this store, just make sure you know your measurements

I was a bit skeptical because it barley had any reviews or photos but I said fk it and just buy it. So I did and when I tell you I was surprised on how it looked and felt I was hooked. I've bought others sites and this one took the cake. It made my hips look bigger and fuller and made my middle waist look like one of those burlesque women. It was long enough to hide my belly pudge . I'm a very happy camper ^

For the price my wife said it was a deal being that it was exactly what she was looking for. High quality item.

I have received so many compliments on this corset! It’s made in like a canvas material and the bones are super hard so it literally doesn’t move/break, I love that the closure in the back it’s made out of a thick material and not lace like normal corsets.

J
J Amethyst

The quality is really good, it fits well, and helps with my back pain! Looks really good too!

I have numerous "store" bought corsets. You know the ones with the plastic bars and that are straight on the bottom and the top. Well, I AM THROWING ALL OF THOSE AWAY NOW THAT I HAVE THIS TRUE CORSET. It is sooo comfortable due to the shape of it. I put it on and had my husband lace up the back for me as tight as he could. What was funny was when he asked me, "Can you breathe okay?" (Of course I could) I replied, "Oh yes, this feels FANTASTIC!" This product is made extremely well and I know if I wore it every day from here on out it would last the rest of my lifetime. The final fit is superb and it does exactly what it is supposed to and is advertised to do with the added bonus of feeling confident. Thank you corsets island for such a STELLAR product!

Mina – Cotton Underbust Corset for Waist Shaping

Mina is one of our most popular underbust corset designs, now crafted in breathable 100% cotton for everyday comfort and serious waist training. This cotton steel boned underbust corset has a longer waspie corset cut with higher sides, giving it a fuller fit that works across more torso lengths than most underbust styles. With regular daily wear, you can expect a 4" waist reduction. 

Built for Daily Waist Training and Real Results

The structure starts with 16 spiral steel bones that wrap the body for flexible, consistent shaping. Four rigid steel plates at the front add extra support where it counts, keeping the corset firm and upright through long wear. The hook & eye closure at the front is clean and secure, built to handle regular tightening without losing its hold.

Inside, a reinforced waist ribbon helps the corset keep its shape over time. The lace-up back comes pre-laced and includes a 5" modesty panel for smooth, comfortable adjustment whether you're tightening for waist training or just wearing it for style.

Who the Mina Cotton Corset Works Best For

Mina is a strong fit for anyone starting or maintaining a waist training routine who wants something breathable and easy to wear daily. The cotton shell makes it far more comfortable against the skin than PVC or synthetic options, so it's practical for longer sessions. If you prefer side lacing over a lace-up back, our adjustable cotton underbust corset gives you that same breathable cotton build with a different fit adjustment.  

It also works well for gothic fashion, vintage looks, burlesque, cosplay, and stage wear. If you're after a black underbust corset for waist training that pairs cleanly with high-waisted skirts, trousers, or layered outfits, Mina fits that role without looking costumey.

It's also a practical black corset for posture support during desk work or long hours on your feet. The steel bones keep your back aligned without restricting movement, making it a solid posture support corset for everyday use.

For anyone who needs extra room at the ribs and hips alongside serious waist shaping, our curvy cotton underbust corset is built specifically for that fit, with the same breathable cotton build.

Finding Your Size in 3XS to 7XL

Getting the size right matters more with a waist training corset than with regular clothing. Here's a simple way to think about it:

If your natural waist is 30", choose the size that closes at 26". That gives you the full 4" reduction with lacing room at the back to tighten gradually over time.

This cotton steel boned corset for women is available in every color you see listed, and the full size range means every color in our underbust corset collection is accessible from the smallest to the largest size without compromise. 

If you're wearing Mina for a costume or a relaxed fit rather than waist training, go one size up for comfort.

Front length is 13", underbust is 8", side length is 11", and back length is 12". The corset suits torso lengths between 9" and 11.5". If you're unsure, email us at info@corsetsisland.com before ordering and we'll help you find the right size.

A Note from Sammy

I'm Sammy, the maker behind Corsets Island. Mina is one of those designs I keep coming back to because it just works. The longer cut with higher sides means it fits a wider range of body shapes without needing adjustment, and the cotton shell makes it genuinely comfortable for daily wear in a way that synthetic fabrics can't match.

Every Mina is made and packed by hand in my workshop. If you want it in a different color, a custom size, or with a different closure, I'm happy to make that happen at no extra charge. You can choose from a silver zip, antique zip, gold hook & eye, silver clasps, flat front with side zip, or front lacing. Just add a note at checkout or email me directly at info@corsetsisland.com with your natural measurements, your desired closed corset size, and any other details.
