There is a certain dress code for NEET exam that the candidates have to follow in order to sit in the exam.

Two criterias that are common for all are:

• Candidates must wear light clothes. Full sleeved clothes must be avoided.
• Closed toed shoes must be avoided. Sandals and slippers should be preferred.

For female candidates:

• Trousers and salwars are preferred. Also clothes should be light meaning devoid of ornaments, embroidery or embellishments.

So, to be on the safe side, try and wear trousers or salwars to the exam so you don't run into unnecessary problems.

Hope this helped. Good luck.
