Brilliant

Yes, I recommend this

Brilliant.Just what I need now that I no longer have any natural padding on my own derriere. I have bought these to make my bicycle rides more comfortable, cycling shorts just help to ease the 'nether regions'. These shorts are so beautifully padded that I hope that I don't bounce off the saddle!

Great boost

Yes, I recommend this

Completely lost my bum after weight loss which isn't a good look in some clothes, got these shorts to give me a bit of shape which they do really well, they give a nice outline under clothes without being too bulky, they are comfy to wear under clothes even jeans and trousers

Not good....

No, I don't recommend this

The shorts are comfy but agree with previous reviews, that state the shape of the bum inserts ( which are removalable) are totally unnatural and give your bum a weird, lumpy, massive shape!!!

Poor fit

No, I don't recommend this

The pads in the shorts for me were to far apart and the look was really fake. Good quality but the pads are not for me

Comfy bum pads but large is too large

No, I don't recommend this

These give me very odd proportions. I bought the largest size as I am plus size and the padding obviously parallel to size but I have a flat bum and these made me look very odd as so padded and protudes so much. Maybe just because I am not used to having a bum but very odd. They are comfy to sit on though. I always have to sit on cushions normally due to my lack of bottom.

I bought it to wear it with a dress at a wedding. It is ok. It helps with the shape but it could be a bit more comfortable.

Great padded shorts, give a nice shape on the rear

Yes, I recommend this

Great little padded shorts. If you could do with a bit of padding on the butt these do the job well. They are quite thick though so probably best worn in the winter months.

Unnatural Shape

No, I don't recommend this

I find the enhancement creates an unnatural shape as it produces a localised mound on the cheek making it look as if a pair of socks have been put in your knickers.
