So, these are good, and these are less good.
If you're skinny and have narrow shoulders, and are probably under 75 kilos, then these are going to give you the hips, thighs and butt you can see in the images in other reviews.
However, if like me you have average width shoulders, are over 175cm and mass more then you should, these will still give you more backside, but not enough thighs or hips to have those be wider then your shoulders, in the way that most western women have hips wider then the shoulders.
I've had mine for several months, and they're always a struggle to get in to, easier to pull on by lathering up with liquid soap and hot water in the shower, downside is though, the water leaks out for quite some time (getting breastplate and hip pants off using body wash or soft liquid soap is much easier then powder).
Once in, thanks to the mass and shoulder size mentioned earlier, these do not give me the width I was hoping for. They do slip down a little, and can chafe at the crotch, if you have any body hair, some shapewear long shorts underneath can make the hip pants more comfortable, including if they're modified to allow use of the interior optional extras,..
The longest I've been able to wear mine has been about six hours, and you can forget about going out on the town wearing them. Play around the home is fun, if they were a little lighter and comfy, you could even try waking up in them to feel more feminine in the morning.
Do I regret buying mine? Not In The Slightest :)

The curves are perfect! I can’t think of any other way to describe them.

The hip and butt enhancement is so strong. I'm absolutely thrilled! The material is stretchy, the fit is perfect, and the realistic feel is amazing.

Quality product in design and construction at a reasonable price. Liked the packaging reflecting traditional Roanyer box and attention to detail in plastic wrapping. Excellent seller communication. Have not worn the pant yet but based on use of similar product I expect it to be fairly comfortable. I would note that the approach to urination catheter and penetrable vagina looks to be more functional than pants from same vendor made year or two ago. Overall I'm pleased with product & seller.

These pants are a lifesaver for anyone with narrow hips. They look so natural and feel great to wear.
