Since you work in a fashion company, your dress should be relatively casual! You have to be a little more open-minded about training for this position. It is recommended to buy a dark casual suit with a white shirt underneath (it should be more casual, preferably with some patterns and a slightly trendier style). Versatile dark jeans. For shoes, buy a pair of casual dark soft fur leather shoes.
The above clothes are generally sold in domestic casual stores. Which city are you in? Personally, I prefer Zara from Spain or HM from Sweden. After all, they are all young people! Take half a day to go shopping, saying that you have time now, but you won’t have time to go shopping later! Men still have to be a little more particular about what they wear
