If should I go for the smaller size** A: I would. I am between a 12 and 14 and that size is spot on for me. I think you would definitely be better off with a 10/12. I should add they are more of a smoothing action than an hold you in type of pants but they are really comfortable and ideal for mummy tummies. **Q: What size is xs a 6 or 36?** A: Hi it depends how you like them to fit really - I’m only 5ft tall & very slim & I like my panties to be very snug fitting so I ordered size 6 & they’re great fit for me & brilliant under trousers/leggings - hope this helps **Q: If size 12 should I order a medium or large** A: Thank you for your enquiry. The Uk12 is normally a Medium size. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Control of the belly! *by S***S on 22 July 2024* I bought to wear under a dress I was wearing to a wedding! They are so comfortable and feel the control on the old belly area, just the right amount of support without feeling too tight. Mine were a bargain price of £10.00.

According to it I am size XS . In reality they are so small they can't fit on my cat. You can not return or replace the item which is a shame. ## Frequently Bought Together - SPANX Undie-Tectable Brief - Comfortable Core Control - Invisible Shapewear Underwear - No Visible Panty Lines - No Show - SPANXshape Everyday Shaping Brief - Core Control Shapewear Underwear - Invisible Under Clothes - Seamless Design - SPANXsculpt Seamless Power High-Waisted Brief - Lightweight All-Day Comfort - Core Control Shapewear - High-Waisted Underwear --- ## 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/63680045-undie-tectable-brief](https://www.desertcart.co.uk/products/63680045-undie-tectable-brief) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-22*
