YES!
Size: Medium, Color: Multicoloured D (5-pack)
I don't give too many items 5 stars, but these are reorder worthy! I bought these a year ago, and am now going back for another 5 pack; not because my first order wore out, but because they are still SO great, I want more! These are my go to for under dresses, skirts, & flowy pants where I want full coverage, but no panty lines! AND bonus, sweat absorption. The leg openings are a tight when I first put them on, but they stay put and are very comfortable. I get my normal size

Comfortable but NOT SEAMLESS.
Size: Medium, Color: Multicoloured C (5-pack), Size: Medium, Color: Multicoloured C (5-pack)
They are soft and well-made, but they are definitely NOT SEAMLESS, which was my whole point in buying them. There are two cross-seams, as well as a fairly thick hem seam on the legs. If you have a problem with inner thigh or genital chafing, you may want to look at a different brand. Otherwise, these are comfortable and well made.
FYI, the ones I received had a matching inner liner, not a white one as some reviewers have noted.

Buying another package
Size: Large, Color: Multicoloured D (5-pack)
Oh my gosh, I love these!!! They are very comfortable and not overly tight. The material is so thin and breathable, very comfortable. Love the colors. Am buying another package! I'm in perimenopause and these definitely keep me cooler than my tradition cotton underwear.
