Pakaian dalam

Celana dalam perempuan.

Celana dalam laki-laki.

Pakaian dalam adalah pakaian yang dikenakan di bawah pakaian lainnya, seringkali langsung bersentuhan dengan kulit. Dipakai agar pakaian luar tidak dikotori oleh keringat, urine, cairan vagina, air mani, tinja, dan lainnya; melindungi tubuh dari kelembaban yang menyebabkan bakteri atau jamur hinggap; membentuk tubuh agar terlihat fit; dan memberikan bentuk lekukan pada bagian-bagian tertentu. Dalam cuaca dingin, pakaian dalam panjang kadang-kadang dipakai untuk memberikan kehangatan tambahan. Beberapa dimaksudkan untuk memberikan efek erotis. Beberapa jenis khusus memiliki makna keagamaan. Beberapa dirancang sebagai pakaian dalam, sementara yang lain, seperti kaus oblong dan beberapa jenis celana pendek, sesuai baik sebagai pakaian dalam dan sebagai pakaian luar. Jika terbuat dari bahan yang cocok, beberapa pakaian dalam dapat berfungsi sebagai pakaian tidur atau pakaian renang. Pakaian dalam yang biasa dikenakan oleh kedua jenis kelamin termasuk kaus oblong, baju tanpa lengan (juga disebut singlet), bikini, thong, dan G-string.
