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.

I love the feel of these underwear. They are true to fit as well. I am 340lbs and bought size 3xl. They are comfortable and not tight in the legs.

Nice for the price
Size: Medium, Color: B004
I really like the LALESTE Women’s Boyshort Underwear overall!
They’re super comfortable, soft, and have great full coverage—perfect for everyday wear. The material feels stretchy and smooth, and they stay in place without digging in or riding up. Definitely a solid option if you like a more covered, secure fit.
My only downside is that they are a bit too high-rise for my personal preference. They come up higher than I expected, so if you prefer a lower-rise fit, just keep that in mind.
Other than that, the quality and comfort are great, and I still find myself reaching for them often!
