Dessous Gallery is not a bad lingerie site, but it does depend on what you are looking to get out of it.
First off, don't be fooled by the whole sign up for free thing. Yes they tell you it is free to join and you don't even need a credit card, but as you might expect, your free membership doesn't get you much. All you get for free are the first three pictures from the photo shoots and the ability to download the short video previews. You also get a set of 30 free pictures with every update email you receive. I guess for not having to pay a cent that isn't bad, but if you are a true lingerie fan and if you want to see all the pictures and download the full videos then you will have to upgrade and pay.
So far there are 84 models available each with anywhere from one to 30 photo shoots bringing the total to around 900 or so. The models look great and the quality of the lingerie is fantastic and it looks rather expensive. Each of them can be downloaded in a zip file. This is great and if you want pictures you will probably never run out of content to look at.
The same can not be said for the video section where you will find 18 episodes. Not only this is a really small number, but these movies are just photo shoot videos and not very good ones at that. The lighting is often poor and a lot of the time the girl's head is cut out of the frame or the angle is bad. The quality of the downloadable video itself is good Windows Media or AVI formats (640x480, 1030kbps; 720x576, 1200k).
They've recently added an awesome search feature. You can find the models based on your preference for weight, height, bra size, waist/hip measurements and more. Both movie and picture updates can be searched by date and keyword.
The good news is that they seem to be updating every 1-4 days with multiple sets (mostly pics). However, the one thing the free membership is good for is it does give you enough of a look that you can see the types of girls and the quality of the content for yourself. I found that for 30$ a month this site is still expensive. It needs to add more videos. In the end it comes down to, like I said, what you are looking to get from the site. If you want a nice balance of pics and videos then this ain't the site for you. Whereas if you have been searching for an exclusive database of luxury lingerie photo sets then go for it.
