Are Transparent Micro Bikini Designs Practical or Only for Fashion?

Last Saturday I was watching a beach vlog where different styles of swimwear were being shown. One of the designs was a transparent micro bikini which immediately caught my attention. I started thinking if such designs are actually practical for use at the beach or mainly created for fashion. Watching people move around in different outfits made me think about comfort and confidence. I realized that some styles look attractive but may not always feel comfortable in real situations. Later I explored more options online. While scrolling many online marketplaces including alibaba I saw many micro bikini designs in different styles and materials. Some looked wearable while others seemed mainly for appearance. Now I am thinking if such designs are really usable at the beach or mainly meant for fashion trends. Has anyone tried them and felt comfortable wearing them?
