GTO outdoor tasks are performed in GTO Dress which is White coloured Short, White coloured T-shirt with collar, PT Shoes or Sports Shoes Preferably white in colour and Socks of white colour. Simply you have to wear all white colour dress.
Your T-shirt must have collar.
Friends some of you might say that I have a T-shirt which is having a strip which is not white or you have a T-Shirt or Short which is not exactly White, or you have Sports Shoes which are not White, then we would suggest you to buy new ones, Gentlemen you are going to attend SSB Interview, even attending it is many’s unfulfilled dream you got a chance to perform there so go there and give your best. More importantly if you wear anything among T-shirt, Short, Shoes or Socks which is not white in colour or not according to specification then no one is going to point you, but GTO will do all the talking with his pen and also you yourself showing that you are not made for Defence by not following rules which you have been told to wear a particular dress code and you are not obeying that code. The onus is yours but we suggest you to wear the above mentioned dress code.
If you wears glasses then you must make sure that you do not loose your specs while doing these tasks as it will create problems for you.
The Choice is yours weather to take White Sports or PT Shoes, but we suggest Sports Shoes as they are more Comfortable while running or doing a Task.
Generally there are shops at Service Selection Boards from where you can buy these items but their rates are quite high for them and are mostly out of stock.
