We (our society) have come a long way to understand feminism. As the culture is under construction of what real sexiness mean, clothing is also reflecting this change. Real women come in all shapes and sizes. As much as we want to look and feel sexy, comfort and confidence is hotter. ALL of this simply paved the way for accepting variety. So, this explains why high-rise bottoms are making a comeback. I have nothing against the flossies but I the comfort of granny knickers.
According to refinery29, another reason why people are thongs sales are declining:
"Even more important than catwalk trends is the fact that this shift signifies different shopping motives: Many women aren't actually buying panties to impress anyone else. Rather, they're buying a particular style simply because they like it."
With that said, let's take a look at the 2015 granny panty (above). The fashion is inspired by the indie culture (almost reminds me of French retro films). Popular styles include lace detail, contrast trim, solid brief, color block and printed patterns.
