Confidence You Can Wear.
Get the smoothing power of luxury shapewear without the "luxury" markup. Look sleek, feel light, and save £50+ compared to the big brands.
Designed To Be Forgotten.
The best shapewear is the kind you forget you're wearing. No rolling. No pinching. No constant adjusting in the bathroom mirror.
We spent months perfecting a silhouette that moves with you—not against you. Using targeted compression and breathable microfiber, we’ve created a "second skin" that smooths your curves while letting you breathe.
You have big goals and a busy life.
Sleekii is here to make sure your outfit is the last thing on your mind.

What if it’s not for me?
We want you to feel as confident in your purchase as you do in our shapewear. That’s why we offer a 30-Day Risk-Free Trial. If you don’t love your new silhouette, we’ll refund your money—no stress, no catches.
Is the fabric breathable for summer?
Absolutely. We use advanced micro-mesh technology that allows air to circulate. It’s moisture-wicking and cooling, making it the perfect foundation for summer weddings and long days.
Is it visible under tight maxi dresses?
No. We use laser-cut, raw-edge technology and ultra-thin microfiber. Our "Seamless Secret" means zero visible panty lines (VPL), even under the most unforgiving satin or jersey fabrics.
How do I choose my size?
Our shapewear is designed to be high-compression. We recommend choosing your true dress size for a "Snatched" look. If you are between sizes or prefer all-day comfort, we suggest sizing up.
How do I wash my Sleekii?
To preserve the compression technology and silicone grips, we recommend a cold machine wash on a delicate cycle. Air dry only—never tumble dry.
How long is the delivery time?
We offer insured shipping on all orders. Orders are processed within 1–2 business days before dispatch. Once your item has been shipped, the estimated delivery time is 6–10 business days.
