And we reckon in the name of the Just a Little video, it is a must that PVC is involved.
Those Liberty X PVC catsuits have gone down in pop history so the band could hardly expect to perform for one last time without them.
And if your memory needs a jog:
In case you have missed it (and we hope you have a good excuse) The Big Reunion is currently on itv2 and shows some of our fave pop bands reuniting for one final show.
Everyone who was amazing in the 1990s is there - think the best CD:UK you ever watched and your probably close.
Atomic Kitten, 5ive, Honeyz, 911, b*Witched and of course, Liberty X all have decided to reunite and it really does make for some A-MAY-ZING telly!
