To give you a clue, yes, raws are "unwashed" jeans. You know, normal jeans, they already wash them and apply all sorts of chemicals and distress them using machines and such. Raws are untouched, unwashed, virgin denim that just received their indigo/black dye. Because they are unwashed, they appear rigid or "hard". Jeans that are lembek and soft are washed jeans. But there are exceptions for this, as you'll learn later.

One exception at the top of my sleepy head now is organic raws, which uses organic cotton. Do read up best way to learn. If you keep asking without reading, chances are, many people will ignore you

bro, just buy it online.  Save you the hassle

Tate&Yoko, a menswear boutique in Canada, something like Self Edge.  The leather patch looks interesting actually

any raw denim will stretch out after wear...dont worry bro..i know this person from singapore who works at this store called very woooonderland who owns a pair of unbranded skinnies as well....he cant button the top button the first week he wears it....instead hold it in with a belt...so just keep on wearing it...try sag them down everyday you wear em and try to stretch the waist so it stretches out..in no time it will stretch out and u can button it...try doing squat exercise in the jeans...that will help too...

Bro, great to see u got yourself the Unbranded. Which cutting did you buy ?  Fit pics ? 
Don't worry if u size down too little or not at all.  If they stretch out too much around the waist , just put on a belt.
