## Description

Looking for a nice rear view? Get your butt in Undie-tectable®. The Undie-tectable Brief was designed to give you a completely smooth look under clothes. The bonded waistband smoothes your tummy while the elastic-free edges offer no VPL, making these undies truly Undie-tectable.

Review: I was so excited with the fit if the product, however after 3 to 4 washes the inner section started separating from the outside and the product looked like a year old. The glue used is a waste of time.
Review: Sooooo....I think they're comfortable, but for $24 I expected that the fabric over my butt would not be see-through. Not that it's a huge deal--no one is seeing them but me, but I thought it odd that the fabric would be see-through. I will not be purchasing another pair. I am a huge Spanx fan as far as other items such as their Bra-llelujah! bras.

## Questions & Answers

**Q: Is 44 the large or XL**
A: no, it’s 40-42 max

**Q: In between a 10/12 uk size with a mummy tummy I’m worried the 12/14 will be too. 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.

### ⭐⭐⭐ Review
*by M***M on 21 November 2021*

I've been buying these for 2 years. The past year (and NO I haven't gained weight, I weigh 5 pounds less!) these Spanx underwear are ALL a FULL SIZE SMALLER than they used to be. Is that to save money so they didn't have to raise the prices? Well I can't tell you that. But what I can tell you is most women do not want to buy size larger when they were a medium or a small or a large! They want what there accustomed to. Spanx just put them back to how they used to be seized, and if necessary charge additional money. It's hard enough being a woman let alone having to swallow you're a whole new size when you're not. Being a female owned company wake up. What a joke.
