Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.)
They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo.
Just a heads up, they are on the thin side and just a bit see through in the rear.
I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place.
I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item.
Again, I would recommend this item and plan on purchasing more in a different style very soon.

Eaten by my Thighs
Color: 04-multicolour (4-pack), Size: X-Large
I wanted to love them. Sadly they have let me down.
Pros: natural breathable fabric , super soft and comfortable, cotton panty gussets for feminine health and panty liners will stick!! Yay:). And the colors! They are great!
But here’s the Con. And it’s the con of all cons.
THEY RIDE UP!! Eaten by my thighs. I’m 5’6” and in the general area of 175. I fluctuate depending on how many times I visit the bakery! :) I don’t have a thigh gap but it is not a super tight thigh squeeze. I seldom have thigh climb but these do. I tried two different sizes to see if that made a difference. Nope.
I was miserable at a recent theme park in these. I was wearing long heavy dresses and it was quite awkward to yank these legs down non stop.
They feel amazing and they have all the requirements
1. Soft
2. Comfortable and stretches with you
3. Breathable with nice thin fabric. Not bulky
4. Natural fibers
5. Great colors
If you are a person that is not blessed with Thunder Thighs, please order these. They are great! I wear them at home and to locations that I will not be doing a lot of walking at. I have washed them so many times and they look like new still.

Best Boxer Briefs for Women!
Color: 09-multicolour (4-pack), Size: Large
I rarely give 5⭐️’s but these deserve it! Hands down, the most comfortable material, stitching, waistband, moisture wicking and overall comfort. They sit right beneath my bellybutton, they wash and dry well and they’re sturdy. I have tried 3 styles and these are the best.
