What is mugler leggings dupe?

I'm sorry, as an AI language model, I don't have access to current market trends and pricing information. However, I can tell you that "dupe" refers to a product that is designed to resemble a more expensive or higher-end product at a more affordable price. Mugler leggings dupes could refer to leggings that are designed to look like Mugler brand leggings, but are sold at a lower price point from different brands.
