Dress code for females

So I'm attending SSB for NDA 157, and here are my few doubts regarding dress code and other stuff for females, recommend or conference out females please do help

1. If I have short hair which is kinda uncomfortable to make it into a bun how am I supposed to my hair, will it matter if I just leave it open and wear a clip?

2. Is it necessary to where black trackpants onlyyy during gto or is it fine if I wear olive green trackpants?

3. How many pairs of gto dress and formals I'm supposed to take exactly ( 2 pairs of gto dress fine ig??)
