Hello, I am a 30 y/o male working as a solutions architect in the IT industry. That being said I am looking to expand my wardrobe further as I am looking to start my own company shortly. I am not sure however what direction to take it. I currently have 3 pairs of dress shoes, all of which are Allen Edmonds Strands in (Walnut, Dark Chili, Oxblood). I have a few sport coats, ranging from navy(silk), brown(wool), beige(tweed), charcoal(wool). A wide variety of various pants to interchange. I also have about a dozen french cuff dress shirts from charles tyrwhitt and brooks brothers in various weaves. Some combination of the above is my normal daily wear to the office. So I guess my question becomes, should I be adding 3 piece suits to my collection or can I get by expanding my sport coat selections? If I am going to pursue a startup and I am meeting with investors, is that the type of event I would need to wear a 3 piece suit or would a combination of the above suffice? I guess I'm trying to determine the practical direction I should take my wardrobe as I dont attend many events that require more formal dress than I can put together currently. Thanks in advance for any help, I appreciate the direction as I am still trying to figure this out.
