Blazer for Men (Posting Again)

Salaam Guys, a family wedding event is coming next month and I want a Blazer, should I get it custom stitching from a tailor (if yes then please share some that can stich well according to the measurements and don't charge too much) or should I get it premade from a local shop or a brand.

I just want a Blazer that fits me well, and fabric is decent, not to plasticy.

My budget is max 6k to 8k
