Dress Code Summer: What to Wear When It’s Hot and You Want to Look Good

When we talk about dress code summer, the unwritten rules for what to wear in warm weather, especially in social or professional settings. Also known as summer attire guidelines, it’s not about looking trendy—it’s about looking put together without sweating through your clothes. This isn’t just about picking a sundress or shorts. It’s understanding how fabric, fit, and formality shift when the temperature rises—and how to still show up looking like you mean it.
