Fabulous!

Yes, I recommend this

Firstly, I never write reviews so that alone is testament to how impressed I am with these bum rejuvenating pants! They are fabulous under my wide leg jeans and very comfortable considering I wear regular briefs underneath. I’m a size 10-12 with skinny legs, small (obviously flat-ish) backside and sadly a bit of a gut! Size medium was perfect for me. Added bonus - even wooden furniture is now comfortable to sit on! Result!

I don't know anyone who has a bum this shape.

No, I don't recommend this

These are rather strange; their shape is unlike a real human bum, because the "cheeks" are quite seperate from each other. They're comfortable when standing but not when sitting because the waste band keeps on rolling down.

Projection, projection, projection ✨

Yes, I recommend this

Without the shadow of a doubt the best booty shorts out there. This is exactly the effect I was hoping for: projection in the medial pole area of my poor posterior. M&S worked hard on these and you can tell: the pads are meant to make one with your bum and not sit on top. The implants are nice and ergonomic, not round flying saucers just hovering. What would have made them perfect is (1) more sizes - an XS would have been nice (2) stronger support/compression everywhere else, are least a medium compression (3) ability to choose your pads separately. (4) While the pads are PERFECTION, I am wondering if it's feasible to make them in a gel ish consistency to mimic real body fat. I do appreciate there might be some weight considerations. Some bra gel pads are quite heavy already 😄 Still, despite its flaws and while I grow back my glutes at the gym, these are a treat. They have become part of me now.

Game changer!

Yes, I recommend this

I cannot believe this garment! I have spent many years hating the fact that I am minus a bum. These knickers / shorts solve my problem. I feel much better about myself in certain clothing. Love them and no surgery required 😂

Shaping is odd

No, I don't recommend this

Thought this could be a good alternative to the Skims one but the padding and therefore shaping is very unflattering - pointy?!

Not for posh events!

No, I don't recommend this

It fit fine and was comfortable until it started to slip downwards. I had to keep pulling it back up!

I HAVE A BOTTOM FOR THE FIRST TIME

Yes, I recommend this

Better than I could have hoped for. Slimline dresses, in particular, hang really well. Very comfortable to wear and the bonus for me, as a sufferer from scoliosis, is I can sit comfortably rather than sitting on bone. A big thank you!.

Love these only wish they came in a smaller size as the smallest is a little big for me. I’m sure small women need the extra bum
