The British tend to call pantyhose "tights" regardless of how sheer they are, while in North America, tights can be used to refer to pantyhose (or a similar garment) made of thicker and heavier yarn of 40 deniers or more. A "denier" is the textile industry's unit of measurement for "linear mass density of fibers." But you don't need to know the official jargon to appreciate Only Opaques so let me continue in layperson's terms.
OnlyOpaques has women wearing pantyhose, tights or stockings that are either a bit sheer but very dense in color or completely opaque. You can't really see the skin underneath the fabric, so it causes you to focus on the overall form and shape of a woman's legs. If the hose is covering her bikini area, what she has (or hasn't) got on underneath will remain a mystery until she decides to peel them off for the big reveal.
I was happy to see a newly designed interface that's now mobile responsive. The content is archived by year and month with the option of filtering just the video or photo updates. So while you can browse their monthly archives, there's no way to browse the updates across multiple months and years. Still, the search page allows you to pull up the HD or Full HD videos and one of the tags is "HD" so you can find them easily. Other tags include nudity level and various details about the model's appearance and attire.
Updates are daily, but they usually add photos more often. You'll already find 1,109 videos and several hundred of the oldest can only be downloaded in SD formats. Just over 50 of the newest come in 1080p and more than 550 others in 720p when you download their best versions. Streams are also limited to the most recent additions.
The 4,120 photo galleries can be downloaded in more than one Zip file with each offering a different size of images - each gallery has at least two high-res ones. You've got an automatic slideshow feature and you can also create custom galleries that contain only the pics or vids, you've selected from within a spread.
The content and models can be added to your favorites. When it comes to giving feedback, you can comment on the vids and pics, and "vote" on them by rating the girl, her outfit and her "tease" (meaning her posing/performance) on a 10-point scale. You'll see a few stats for many of the girls in the model index and often they've answered long-form questionnaires to help you get to know them better.
An interesting enhancement to the user experience is their "FastTrack" system that allows early access to upcoming scenes. You earn 10 FastTracks for every (consecutive) month of membership and additional ones can be earned through interacting in their forum. You can also buy additional FTs in packs of 10 and they never expire (only a limited number of the free ones roll over each month).
When you join first join, Only Carla and Only Melanie are included as bonus sites. If you stay a member for at least 90 consecutive days, you'll be upgraded to VIP stats and have access to the rest of the Only All Sites network, including Only Silk And Satin. If you don't want to wait for this loyalty to kick in, you can simply purchase a more expensive VIP membership instead of the standard one.
Only Opaques is unique by focusing on a very specific type of pantyhose and stocking porn. They also deliver their frequently updated content in large quantities and in high-quality formats. So much so that you'll reach that three-month VIP loyalty upgrade in no time flat.
