The dress code at The Ivy restaurant in central London is smart casual.
During fine weather, tailored shorts and short-sleeved shirts are permitted, but long-sleeved shirts are required at all other times. Athletic attire of any kind is not acceptable.
Ties are not required and smart dark jeans may be worn, but as dining at The Ivy is a special occasion for most clientele, many will make an extra effort to dress for the occasion.
