100 Key Apparel Merchandising Terminologies and Their Definitions 

Let’s imagine your dream job is apparel merchandising. And you got your dream job in a buying house or in an export manufacturing company after completing your course. While studying, you learnt what would be your job descriptions and day to day job roles. All sounds good. In practice, when you enter into the industry with a professional role, you need to deal with many challenges. Once such a challenge is industry specific terminologies and their actual meaning and the application of each key terminologies. You must learn them as quickly as possible to give your best performance on the job. 

Outside your job responsibilities, you need to participate in many discussions and follow communications with internal teams and possibly with buying agents and buyers. Once you know the apparel industry terminologies, you can communicate with them very well. You will understand the discussion faster.  

In this post, I have posted 100 common apparel merchandising terminologies and their definition in the context of apparel manufacturing. Related to pre-production, product development, fabrics and raw material, garment costing and pricing, garment construction, garment productions & execution, Quality related terms, logistics and supply chains. Not only that, I have given links to other resources that explain more about these subjects.
