Hello student ,

As you not mentioned about in which exam you are asking fir but still recognising about NEET entrance exam , you can wear it but make sure that it has only brand name and it should be light coloured  as by the guidelines of NTA about the dress code in NEET exam , you have to wear is only half sleeves t shirt , lower and simple slippers . Further your t-shirt should not have any embroidery work on it . Beside this as you know pandemic is going on then you have to take a water bottle , face mask and one 50 ml bottle of sanitizer with you on the examination centre  .

Hope this information will help you !

Good luck !
