For men: Ibiza clubs usually expect a smart-casual vibe at night. Think slim-fit t-shirts, polos, or breezy linen shirts paired with chinos or tailored shorts. Casual sneakers are fine, but skip the running shoes. Leave the beachwear, like flip-flops, sleeveless vests, and football jerseys, for the sand. If you're heading to daytime venues like O Beach or Ibiza Rocks, swim shorts work well, just throw on a shirt. At more laid-back spots, the dress code is relaxed, but you’ll still need a shirt and closed footwear after 7pm.
For women: Stylish but comfortable is the key. Fitted dresses, co-ords, or jumpsuits are popular choices, and for daytime pool parties, you can wear a bikini—just add a chic cover-up. Sheer outfits should have proper lining, and instead of heels, go for platform sneakers or block sandals (your feet will thank you). Costume accessories, oversized bags, and spiked pieces might get turned away at the door. Nights can get chilly, especially indoors with the AC blasting—bring a light jacket just in case.
