What phrase is appropriate when discussing clothing size with a customer?

The best approach when discussing clothing size with a customer is to ask, "Have you worn this brand before? What size was most comfortable for you?" This question focuses on the customer's past experiences and preferences, which is a respectful and effective way to help them find the right size. It encourages an open dialogue about their needs and comfort without making assumptions or potentially causing embarrassment.

This method acknowledges that sizing can vary between brands and fits between styles, helping to establish a more personalized shopping experience. It puts the emphasis on the customer's comfort rather than on their physical appearance or size, fostering a positive and supportive interaction.
