Dear Sir / Ma'm, yes you can wear jeans in the JIPMER entrance test. It is better advised to avoid wearing any kind of belts or full sleeves shirt or tee-shirt as the authorities might raise an objection to it. You must also avoid using any clips or clutchers to tie up your hair, as if you do so they will make you open it, so, better tie up your hair with a rubber band and nothing else.

Hi Aspirant, 

there are no strict guidelines about your apparel for JIPMER. I would suggest you to avoid jeans with metal buttons though.

You can find the guidelines about do's and don'ts here for your reference:

Hope it helps,

All the best!
