Reviews Summary
Customers say these sheer fly-front briefs are incredibly comfortable, sexy, and well-fitting. Many appreciate the soft fabric feel and attractive appearance, with several mentioning they've purchased multiple colors. The sheer material is frequently praised for its sensual look while remaining comfortable for daily wear. Common feedback includes great fit and comfort, though some note the sizing runs large and recommend sizing up. A few customers mention the pouch could be roomier, and some wish for additional color options like black or brown. The fabric is described as delicate, making it less suitable for strenuous activities.

    Super sexy brief! I love

    Super sexy brief! I love the sheerness of this brief, its more of a fuller cut brief but it is comfortable enough for wearing during the day. It is delicate fabric so I wouldnt wear it for anything too strenuous. But I love the sexiness of the brief.

    Love but just be aware of fit

    Love these, they look great and are comfortable.

    I originally went with my normal size L but due to the fabric they fit slightly large. I ended up exchanging for a M and bought more pairs. One of my go tos now.

    Shout out for the amazing customer service on the exchange!!
