I haven't really gotten around to looking yet but I'm going to buy a couple more suits this summer. I already bought a 3 button made to measure black armani, which hasn't yet arrived. Next year I'll be interviewing for student jobs in investing/finance and the year after analyst positions at investment banks This summer I'll be wearing suits at my job, however it's a much more casual setting as I'm working for my parents and I oversee staff, deal with client related problems and do accounting stuff at a hotel. So I'm buying suits for this summer, but the most important thing is that they need to be appropriate for the IB interviews I'll be doing not too far down the road. Obviously one of the new suits i get will be a navy pinstripe. A couple questions: 1) 2 or 3 button? I'm 5'11" and slim. My preference is 3 but I'm not sure if there are any "rules" I don't know about for IB interviews. I know the older guys usually wear 2 button but what about the younger people? Is 3 button acceptable in the IB world? I know they're picky as hell about how you show up for your interview.. I will surely have the suit for 2 years so I'm thinking about IB while I'm buying my suits for this summer. 2) Is there a rule about the spacing of the pinstripes? When i was shopping for my black suit i found a 3 button navy pinstriped versace which fit me very well and looked really nice. The pinstripes were quite closely spaced though (.5-.75cm or so apart i think). It seemed more a suit to wear out at night or something that would look good with even just a white t-shirt underneath, although that's just my subjective opinion and I haven't ever been in a corporate environment so I don't see what people wear and have never really payed much attention to it. Does this sound right or does the spacing of the pinstripes have no bearing on where it would be acceptable to wear the suit. 3) What to get for my third suit is sort of up in the air. The navy pinstripe will be my interview suit. For this one though i have a bit more room to breathe. However I'm thinking I will probably want to wear a different suit to second interviews (again for IB) so bear that in mind. It would be nice to stray away from navy for this one but I really don't know what would be appropriate for such a suit. I don't really need suggestions on brands since i know what fits me best and which i like. I need suggestions more in the way of which style/color of suits i should go with for my needs. Thanks.
