The cloth portion is made of 90% Polyester and 10% Spandex, and the waistband is an elastic band. Small portions of the band are stretchy, but are mostly rigid. The material that makes up the front and rear portions is nice to touch. It's not quite silky but it is smooth, and it'll pick up and hold other scents for a while but didn't come with one of its own.
This harness is designed to be worn like a thong. It's got a pouch in front to hold dildos of all shapes and sizes, with or without balls, and a single o-ring. The o-ring can't be swapped out, but it's made of silicone (at least according to the packaging) and does stretch so you can accommodate rather girthy dildos. The front pouch and the back piece of fabric are both made of the same material which according to the tag on the inside of the harness is 90% Polyester and 10% Spandex. The front pouch measures about 6" tall (without the 1 1/2" tall waistband) and about 3 1/4" across at the o-ring. The back of the front pouch has a flap design that will close over the base of whatever you've got in the harness, although it's relying mostly on it being pressed against you to keep everything solidly in place. The back portion is about 5" tall (again without the waistband) and about 3 1/2" wide.
Connecting the two parts is a strap with snaps that can easily adjust the harness to be longer or shorter in the crotch area. When you get it, it's set in the middle and gives you about 6". You can make it as long as 7 1/2" or as short as 4 1/2". The waistband is completely adjustable thanks to the Velcro straps that open on each side like a side tie panty.
The overall craftsmanship isn't too bad, although it's not what you would expect from something you intend to have around for a very long time. After just one washing, a few of the snaps started to show rust. There were also a few loose threads, but they were very easily taken care of.
The packaging claims that this will fit all the way up to a 44" waist, and it should fit very close to that. It all depends on how much you want the one Velcro strap to overlap the other. There is a little bit of stretch in the waistband near the front portion, so you might have to stretch it a bit, but you should be able to fit actually up to a 44" waist. If you're right near the border though, I would think about how much you'd be ok with it possibly digging in and decide from there.
The back half of the waistband has Velcro all the way around it, so you can easily fit pretty much as small as you want. I'm about 34" around the top of my hips where I wear this, and it sat very comfortably on me without any extra Velcro hanging over the sides or anything like that.
I think that most people will be able to wear this without many problems.
This harness performed remarkably well for everything I was using it for. I soft packed for a day around my house to see if it was possible to do it comfortably, and I didn't have any issues with it. I was also able to use this to peg my husband and it was very comfortable in every position we tried it in. The dildos stayed securely in place, and I didn't at any point feel like the harness was going to come undone or the dildo was going to move. The base hits above my vagina but doesn't go any higher than my pubic hair would when I usually wear it, but you can adjust the fit so that it hits lower if you want to try and have the base of a dildo simultaneously hit your clit.
While the o-ring isn't replaceable it is stretchy, which will still allow you to use a wide variety of dildos. The largest dildo currently in my possession is Marco Blaze, and this harness easily stretched to accommodate Marco's girth, and balls, just fine. The suction cup did stick out, but with a larger base like this it's easier to stimulate the clit without having to readjust the harness much.
Care and maintenance is pretty simple for this harness. To clean it, you'll just hand wash it in cold water and lay it flat to dry. You can hang it too if you want, but keep the Velcro in mind if you do. You'll also want to keep the Velcro in mind when you store it, since the Velcro can very easily attach itself to the fabric and cause pilling and other unsightly marks. It doesn't seem to affect much more than looks though. Store it in a drawer, folded neatly in a bag, hang it in your closet, or keep it with the rest of your delicates.
The packaging isn't discreet, but isn't overly tacky either. The front shows a mannequin wearing the harness and says "Fetish Fantasy Elite", and that it's compatible with any silicone dildo. The back has a bit more information about it and shows another front view with a back view of the harness with one of the Fetish Fantasy Elite dildos.
There's enough on the package to figure out how to use it, but nothing other than the plastic bag that holds the harness inside. On the bottom of the box there's a QR code that you can scan with a smart phone, although I couldn't get my phone to scan it well enough to figure out where it went because the code is so small.
Overall I like this harness a lot. It's easy to figure out and use and the price isn't all that unreasonable. Could it be better? Sure. But it could also be a whole lot worse. I don't like how fast the snaps started to show rust, but I do like how easy it is to use, how well it works, and the fact that you can use such a wide variety of dildos with it.
I'm personally not that big a fan of this being in a g-string style, but that's not the end of the world. I think the only bad thing I can really think of is the fact that the soft material snags easily if it comes in contact with the Velcro. Otherwise it's pretty durable, easy to use and figure out, and will fit such a wide range of sizes that I can't knock it too badly. If you're careful with the Velcro you won't have any problems.
