Emma Frost is an attractive blonde with dark blue eyes who is very conscious about her looks. Thus, she is always seen clad in expensive, classic-style clothing, mostly in white colors. Also, being something of an exhibitionist, she sometimes, even while working, wears white clothing only covering her most private parts, showing lots of skin. An example is a white cotton lingerie set complete with leg step-ups.

While in her diamond form, she appears to have a glass-like skin.
