To say "so-so" in Spanish, you can use the phrase "Está bien" or simply "sí" (pronounced ñe). For a more casual tone, try using "cada" (KAH-dah), which is an expression that roughly translates to "good enough". If you want to compliment someone on their outfit, you can use phrases like "Me gusta tu ropa" (MAY-goo-tah too ROH-pah) or "Eres muy estiloso/a" (EH-res MOO-ee eh-SEE-lohs/eh-SREE-lohs).
