I must use my powers of fashion to let you know... my friend i would even wear a really cheap suit before trying the blazer look... its unfortunately all about conformity and they may spend half the time thinking about how odd you look. im pretty attuned to this as my wife wears hijab (modest clothing and head scarf) and who knows, she may already be scrutinized about this on her interviews.
You could drop $1200 for a pal zileri, canali, or armani, or prada, you could drop $800 for boss suits, $500 for abboud etc.....$300 for Men's Wharehouse
BUT my friend You can get suits cheaper than 300.. believe it or not... google "K&G" for one near you... or for example theres an "urban" store called Harold Penner's here in Kansas City that sells CHEAP suits 2/$300 etc, search for one in your city, look online for cheap suit deals in your size... dont know your size, goto a dept store and have them measure you, then order, get it tailored....or even worst case scenario... if i had to i would go and find an amazing deal at a "vintage" store or a thrift shop... get em dry cleaned and tailored and you could get a suit for less than $100!!!
can i get a booya?
