I need a blue blazer for work (conservative employer), ok to get 2B with peak lapel?

The DB is definitely a no go and while I love peak lapels on SB suit jackets, on sports jackets I would not got that route, especially in a more conservative environment.

too flashy. Not something you can wear day-in-day-out, IMO

I suggest differentiating yourself with the blazer via quality and fit. I would try a 2 1/2 button, some pick stitching and a suppressed waist. You might try enameled buttons. Throw in a well chosen pocket square and you won't look 'regular guy' even with a blazer. Wear wool trousers and french cuff shirts (perhaps opting for silk knots) to complete the look.

I think a 2B peaked lapel blazer will be perfect. It's just the right touch of style mixed in with professionalism IMO. Especially if the general office wear is khakis and polos.

I love the look of peaked lapels, but they're too fashion-forward for business. Differentiate yourself with an interesting fabric, a great fit, and different buttons, perhaps smoked MOP.

Excellent advice.

Given the informal dress code, then getting a peak lapel blazer is I think a good idea to start developing your own unique personal style.

How many people actually notice (as in say or think, "hey, that dude's lapels are different") the peak lapels? My guess is people would feel like something is off, but not really notice it. If it's otherwise a normal looking blazer, I don't think it's a huge deal.

Normally I would say that is overkill, but here in Chicago our PBS channel has running the show with Guy Kawaski(sp) , the guy who wrote the the Rich Dad - Poor Dad.

He has a Peak Lapel Black or Navy Blazer and in the show he dresses it down casually and in the promo dressed up with a white shirt and dark tie, and they both look elegant and normal.

Thanks, I think (What's QFE?)

OP: keep in mind that peak lapel blazers look better closed than open, at least in my world.

I'd save the peak lapels for your formal suits and not a blazer. Peak lapels would only lead to the formality of a jacket that by its very nature denotes business casual.

Though not finance, I work in a pretty conservative office too. Most people are somewhere between business dress and business casual. They come in in either a shirt and tie or a jacket and tie, with suits reserved for days with important meetings, presentations, etc. This is especially true in summer. What do I wear? I wear a suit, and lose the jacket when I get in in the morning. Why? Because I really love suits. It doesn't bother me to be the most formal, and I would rather spend my money on good suits than good pants/jackets because it's what I enjoy more. And, for reference, I, too, am the new hire. I say wear whatever you want (that is reasonable). If you like suits, wear a suit and no tie, etc. As long as you are comfortable in it, who cares (unless someone tells you specifically not to).
