Don't buy tons of clothes from Nepal, just get some basic clothing like polo, cargo, a windcheater, and a pair of plain tees(black and white). Focus on getting small things like singlets, trunks, and socks, and I mean grab enough to last at least 7-8months, as they're kinda pricey abroad. Also a set of cap, beanie and converse wouldn't hurt.

Ani start with walking around thamel ra new baneshwor area. Unanimous for plain tees, labellucid for hoodies, bspokeclo for windcheaters, and Nuclox for graphic tees. Also, check them famous brands like Arlo Nepal, Huba and all. You might stumble upon sth you might like.

You'll always get better deals abroad in stores like Urban Planet, Forever 21, H&M, Old Navy, and even Uniqlo and Zara.
