Comfy everyday undies
These were really comfortable for everyday wear and didn’t dig in or roll throughout the day. The quality of the cotton felt soft and breathable while still having enough stretch to fit nicely. I also liked that they stayed fairly seamless under leggings and thinner clothing. Good balance between comfort and practicality. I’ve worn them several times and no sign of wear and tear thus far.

So comfortable throughout the day
These panties offer exceptional comfort. I typically feel cautious about lace on underwear, unsure of how it will feel until I try them on. Fortunately, these feel like a second skin, with none of the irritating creeping sensation that forces you to adjust your underwear throughout the day. The colors I chose are neutral and attractive. The soft cotton fabric prevents bunching or tightness, allowing the panties to stretch comfortably with my movements. They sit around the hip bone, providing a look that is both pretty and subtly sexy, without the unappealing feel of a thong—which I strongly dislike. The lace detailing is delicate and elegant, not flimsy or likely to fall apart over time. After washing, the panties retained their shape and color exceptionally well. I separate my laundry by light and dark colors to avoid fading, and I didn't notice any discoloration or fading after washing. I washed them in cold water and dried on high heat, and they showed no signs of shrinking.

Beautiful Panties for and Excellent Value
These are beautiful panties for the price! I truly love their packaging. As they make one feel beautiful and it is very inclusive. They were arrive in an hygienic plastic packaging within a colorful envelope. All of the underwear are shaped in bikini style, and they also have a beautiful lace trim all around. I really like the warm colors of this pack that I chose and I also enjoy the beautiful feel and look of the lace they are made out of. Really good quality and I love how breathable and comfortable the cotton is. Depending on what one is wearing these cotton underwear may be somewhat seamless under clothes. They fit really well and they are super comfortable on. I really like the quality of these and the value. I really enjoy the undergarments from this brand. I recommend!

Soft, stretchy, comfortable!
As a CIS male, I made the switch to women's panties years ago... they just fit better, don't ride up anywhere, and hold the 'boys' better. These panties are no exception. Being a larger man physically, I usually order panties in the XXL to 3X range. These XXL just fit. They are made from 95% Cotton and 5% Elastane, which I have come to prefer (the elastane) in underwear as they help regulate temperature. The lace is not bothersome at all, and the back side show your butt like a pair of cheekies, but give plenty of coverage. The colors are different from what I normally wear, but I'll take comfort over fashion anyday, especially when dealing with down there. The fabric is soft and stretchy, and I was able to wear these all day without having to adjust much at all. Nice panties for this man!
