Final answer:
The associate should ask the customer about her specific fabric allergies and recommend a scarf made from synthetic fabric.
Step-by-step explanation:
The associate should ask the customer about her specific fabric allergies as the next step. Understanding the customer's specific allergies will help the associate recommend the appropriate scarf material. The associate can then recommend a scarf made from synthetic fabric, which is less likely to cause an allergic reaction. It is important for the associate to prioritize the customer's needs and accommodate her allergies, rather than ignoring them and showing her scarves made from natural fabrics.
