Retail is such as big beast in regards of options! I spent 3 short years in Retail with Australian clothing company CottonOn and loved it. I worked at the head office but also spent a lot of time in stores. I worked my way up to be Australian Merchandise Manager which is basically a Supply Chain role which interacts with every department / role in Retail.
First decision is do you want to work in the store, head office or warehouse? 2nd decision is the role e.g. Buying, Visual Merchandiser, Warehouse, Store Manager, Supply Chain. Operations (HR/IT/Finance ect) 3rd decision is finding the right company. Good luck!
