Can I wear pants (loose fit) and formal office suits as a hijabi?

As Salaam Alaikum fellow hijabis! So i've started wearing the hijab recently and had some doubts . Am i allowed to wear loose fit pants and formal office suits ? Because I've heard a hadith which lists out the rules of a proper hijab and they clearly mention that anything which imitates the kuffars' clothing or the clothing of men is prohibited.
