    I have tried a lot of eye masks in the past (weighted, cooling, leather, ones that don't lay on the eye) and this one is by far the best! I was skeptical of the price, but it is definitely worth it.

    I work outside 6 days a week in the elements. Sun damage is inevitable. However, this summer I have used these sleeves every day. My arms have no sun damage at all. They also help cool me down. The Best Buy of the summer!

    I really like these! I wanted silk masks to help with my skin (mask-ne, its real). They feel great and are comfortable to wear and easy to breathe in. Look cute too! The ear straps adjust, which is great. Delivery was pretty quick, too.

Get the dress!

Needed a dress for wedding didn't have much time to shop around. I Don't like ordering clothes off the internet but read through the reviews. This dress fit great. Made me feel great and was super flattering. I'm about a size 8/10 155lbs, 5'4’ DD ordered a Medium. Fit like a glove. No bra needed. Felt supported in all of the right places. Tones of complements. Even after a night of eating a ton and drinks, still felt great wearing this dress. The fabric holds you in with out it feeling uncomfortable. Definitely recommend this dress.

Incredible Dress!

5'8, 195 lbs, waist 35 inches, 36DD. Purchased split black in XL.Y'ALL- I've been wanting to hop on board the satin slip dress train for a while, but I've been nervous to pull the trigger because it's hard to tell on the internet if the satin is decent quality, and because I'm curvy and self conscious about my tummy.Let me tell you, one pair of spanx and this dress later I felt like a freakin bombshell, which is amazing because I currently have the lowest body confidence I've had in years. Husband was drooling.Fabric- this satin is pretty thick and a little stretchy, which was a pleasant surprise. Definitely not see through, and I was able to comfortably sit through a three hour opera. Has a very nice shine, but definitely does not look cheap. The stitching is well done and the straps are STURDY. The zipper should probably be a little more heavy duty, and there is no hook and eye, so I will be adding one in future to help get the zipper up. Once it was zip everything was great, but the satin is slippery so I had to have my husband do the actual zipping while I helped hold the sides together. But for $30? Don't even care.Fit- this dress went about 3 below my knees while standing, and sat just above my knees when sitting. The waist is very fitted, but the hips allow a lot of space. It was wild, it looked tailored right of the packaging. The bust area fit really well, and the fabric is sturdy enough that I was able to comfortably wear this dress without a bra. The ladies were supported, not squished, and I wasn't worried about the nips. The slit is towards the back of the dress, which I didn't realize looking at the pictures, but I actually really like it! It's just behind my left leg, and when sitting, you might not notice there's a slit at all.Note- not sure how this dress would fit on a slimmer body type, because I don't have one- the neckline would probably slouch in a really pretty way on a smaller chest like in the pics, but the hips might bag, it's hard for me to tell.Just purchased in the rust color as well, this is going to be my go to wedding guest outfit this summer! It rides the perfect line between casual and formal. I cannot believe I got this stunner for such a great price. Buy it!Will absolutely update with photos, unfortunately forgot to get a pic!

WOW!! Just WOW! Flattering, slimming and sexy!!

I'll try to add a photo later. Tried this dress on, I am 5'6"/165 and ordered a large in red. WOW! I have an apron belly and this dress hid it all. It's not a thin satin either, its a thick material with a nice stretch and holds you in place without accentuating and lumps and bumps. Very slimming and sexy! I'm tempted to order in another color also. Get the dress!!!

LOVE this dress!

I am not particularly girly and don't wear dresses often, but I plan to purchase this in additional colors because I love it so much. I wore for the first time tonight for date night with my husband- I received tons of compliments and the dress was comfortable enough to wear most of the day in the despite the summer heat.I am 5'7 with an athletic build, 155lbs and typically wear a size 10 - I ordered a size large and love the fit (I could have probably gotten a medium, but I think it being just a little big is more flattering).

Just wow!

This dress is fantastic! I absolutely love it! The color is so flattering, the length was perfect for me, and it made my curves look really lovely! The only thing bad thing about this dress was that it was a little loose right underneath my armpits. I tucked the extra fabric into my bra so that it wouldn't hit my armpits. I think if I would have loosened the straps on the dress it would have fit better but I need all of the support I can get from a dress! I will be purchasing this dress in more colors! 11/10 recommend

You May Also Wonder...

Are your products 100% pure silk?

Yes! All Osorsilk products are made from ultra-luxurious 100% Pure Mulberry Silk. We use the highest grade (6A) long fiber mulberry silk, with a thickness of 22 momme and enforce the strictest quality guidelines, including non-toxic dyes.

Where are your products manufactured?

Please feel assured that all of our products are made of 100% Grade 6A mulberry silk in China, which is safe and healthy. No chemicals are added in our production process and the use of any machinery or chemical additives that could potentially compromise the quality of our silk has been strictly forbidden to ensure the perfectly soft and smooth feel of our products. Thousands of pillowcases have been sold to our customers in 6 years and we will always provide the best products and services to our customers.

What does Momme mean?

Instead of thread count, silk fabrics use momme – i.e. fabric weight to measure the quality of silk fabrics. Momme weight describes the weight of 100 yards of silk, 45 inches wide, in pounds. Higher momme means there are more strands of silk per 100 yards of fabric, therefore making the product heavier. So if we weigh that fabric, and say it’s 19 pounds, the momme would be 19-momme. The higher the momme, the higher quality and more durable the fabric is. Momme can range anywhere from 11-momme to 25-momme.
