I think the stud trend looks very edgy and can really vamp up a boring outfit. The spikey shoes in the first two pictures are really sick and I think that if they were worn with a chic little black dress, the outfit would be so complete and totally transformed. I love how with just a simple pair of shoes, an outfit can go from drab to high-fashion. However, a lot of these spiky shoes go for $200 and up, which makes it hard to stay on trend without going bankrupt. So, I found a few shoes that are very inexpensive, but look really nice.

Also, try making your own studded design! Get some studs of a fabric store website like mood fabrics and start spiking up your heels, bags, tops, and whatever makes you feel more edgier. It's cheaper and more unique! xx
