I am short so it just came up way too high to do any good. I tried placing the band where I wanted it to hit but then I had 2 extra inches of crotch fabric dangling between my legs. I wish I could find something for us short torso women **Q: I usally wear size 8 panty should i order a xl?** A: A “panty” size 8 is a XXL **Q: I’m size 16, what would be the best size to purchase? Want it to do its job but obviously don’t want it to give me a muffin top either. Please help** A: Get an Xlarge - your concern is exactly what i wanted. If they have a larger size like an XX - i would do that. It still does its job but it is so much more comfortable. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Comfortable, lightweight, smoothing *by on Reviewed in the United Kingdom 13 July 2025* Lets start with what I was looking for, a lightweight high leg pair of undies to smooth my tummy under a skirt for an evening out, in the middle of a hot summer, where I would be eating. Did they deliver? 100% yes. Sizing, I followed the size chart and chose XL (size 20) and although when I unpacked them they looked a little small they fit perfectly and were very comfortable. Zero roll down, they stayed in place and were easy to replace when visiting the bathroom. The thong was comfortable and I found the overall quality to be good. Now, lets get honest for a min Ladies. No piece of elasticated fabric is going to turn a size 20 into a size 12! However, if you are looking for something Lightweight, fuss free, to give you that little bit of extra confidence and disguise those peskie tummy rolls I would recommend these. They performed the function I was expecting and the colour (Cafe Au Lait) worked well with no shine through under a white skirt. I paid £14.75 for these on offer and thought that was a fair price. ### ⭐⭐ Not for tall people and not full briefs its a thong ( wasn't really clear) *by on Reviewed in the United Kingdom 25 January 2021* First of all It wast really clear that it was a thing I was buying . So support for butt at all ( in fact it cuts it off and makes it stick out a bit more)Amd they ard not made for tall people. The waist band is approx 3 inches so doesn't really fix my problem but inhances in and out bits.If I get a size bigger they will be baggy at the crutch maybe I'll try and find full briefs somewhere but at that cost per pair I'll run out of money and no pants to wear !! ### ⭐ very stretchy material,not recommended *by on Reviewed in the United Kingdom 20 May 2025* Very stretchy material. I took a size smaller. They don't squeeze the belly at all. I can't return them or swop. I DO NOT RECOMMEND!!! ## Frequently Bought Together - SPANX Undie-Tectable Thong - Comfortable Core Control - Invisible Shapewear Thong - Women's No Show Thong Underwear - SPANXshape Everyday Shaping Thong - Core Control Shapewear Underwear - Invisible Under Clothes - Seamless Design - SPANXshape ExtraOrdinary Thong - Sculpting with Compression - Women's Shapewear Underwear - Recycled Nylon Fabric Blend --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/690286220-spanx-womens-undie-tectable-trouser](https://www.desertcart.co.uk/products/690286220-spanx-womens-undie-tectable-trouser) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-30*
