I need help in finding a blazer, preferably navy, and I'm asking for help from the style forum fashion gurus. I know next to nothing about blazers and have searched Ebay, STP, Bluefly, etc. to confirm this. I'm not sure I would know one from another. I live in Phoenix, where we have 9 months of warm to hot weather, so I'm looking for lightweight. I want the blazer to be versatile, I'd like to wear it with slacks as well as jeans. I'm 5'7", 29" waist, and weigh about 150. I wear a 40 short in RTW coats. Can you fine folks give me some ideas and/or suggestions on finding something that would fill my needs? This won't be worn all that often, so I'd like to get the most "bang for the buck". While a $2000 Brioni might look great, spending that much doesn't make much sense if I'm only going to wear it a dozen times a year. Thanks for any help.
