Thrift store shopping is literally the best! You can find unique items and clothing and for less than in first-hand stores. During my vacay to Hawai'i, I went to a bunch of thrift stores (almost all of the ones available on the island) and found these unique plant-themed pieces.
I found plant-patterned pants, tank tops, and a dress! Each piece was under $10, and I only spent about $100 for all my thrifted clothes from the trip (including the non-planty items not shown here!) This shows how you can be on style and on a budget. Here's how I wore them.
I hope this gives you planty of inspiration ;)
