Need a blazer

[jamone]

Hey guys im new, basically i need a blazer to wear with a vintage t-shirt and jeans with brown shoes when i go out clubbing/drinking. I want the blazer to be navy blue and pinstripped (i would like the pinstripes to be thin and faint and not to many 2 close together) but because ive never bought one before i dont know to much apart from that. Ive been looking around for one but some are made of cheap material and look cheap or i cant find the right colour. Anyways, does anyone know where i can get one from like ive mentioned above???

Thanks

Well i recently bought a suit jacket from Topman and a 40 inch chest fitted me best.
