A blue dress is always in style in anime. It strikes the right balance between being classy and friendly. You often see it on characters who are calm, collected, or have a high rank. For instance, the classic battle gown look or the mysterious heroine by the sea. It is a color that means calmness, trust, and sometimes sadness, which is why it is often used in emotional key visuals.
There are a lot of choices here. There are light, airy pastel blue sundresses on one end that scream summer vacation and innocence. People usually wear these with straw hats and white clouds to get that old-fashioned look. You can also find deep navy and sapphire formal gowns in fantasy ballroom scenes or gothic lolita coordinates. Artists love to show off different textures, like flowing silk water effects or stiff, military-style fabric. The cool colors look great on light skin or warm backgrounds.
Blue is another color that makes you feel like you are in a fantasy world, but it is not too strong. It works just as well for a date outfit as it does for magical girls who use ice or water powers. The blue dress tag is a never-ending source of high-quality character art that will make your walls look new and stylish without being too loud.
