Where can i find good affordable pants in Mumbai?

I (20M) am tall and lean so its almost impossible to find pants that fit me both lengthwise and at the waist. I already have baggy jeans and cargo pants in my wardrobe but i wanted to get myself some trousers or idk something new basically. Since im a student my pocket isnt too big, does anyone have any shop/location recommendations? I dont mind thrifting i just have 0 clue about where i should look. I checked Lokhandwala Market in Andheri and they had pants for 3-4k ToT
