As the name might suggest, pearlcore refers to the use of pearls and iridescent accents or beads that resemble them. The micro fashion trend (which also extends to home decor) involves embellishing everything from a tank top to your favourite sneakers with the classic gemstones. While there are many pearl-encrusted pieces readily available to shop, you can also take the DIY route by sewing the pearlescent beads onto cardigans, jeans, bags and shoes.
