## 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.

### ⭐ Size not accurate
*by A***R on 20 October 2025*

The size guide is not accurate. 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.
