Hello. I recently started to give in to sportcoats/slacks ensembles for casual fridays to blend better with others at the new job (it was suits 5 days a weeks before). I'm liking it a lot, but I need some suggestions. I'm in my early 30s, in case that's a factor. I guess I'm well set on sportcoats for now (4 total, 2 per season, woolen for winter and cotton blends for summer, 1 navy and 1 brown/tan per season, all patch pocketed on the sides, all solid but textured - eg herringbone, nailhead, twill, etc). Not planning for grey odd jackets anytime soon. The main issue is maybe that I don't have a proper, worsted blazer at the moment, since I'm in a suit and tie for the rest of the week, will extend that to friday if needed, and I like the change of pace of more casual options. Is this nonsense and should I consider getting a proper navy blazer priority number one? For slacks, I have mid grey flannel for winter, tan linen for summer, plus some decent cotton chinos in khaki and navy. I don't think I'd like worsted wool slacks with the above sportcoats as I feel they would clash in formality. Is there anything I could get in grey for summer which would go well with cotton sportcoats? How could I add variety in general? For shirts, I obviosly have various dress ones: white/light blue, poplin cotton, semi-spread collars, all MTM. Then I have casual, office-appropriate ones: white/light blue OCBDs for winter, white/light blue linen BDs for summer, some BD bengal stripes, all RTW. The thing is, I feel dress shirts, lacking any kind of texture, are too formal vs the above sportcoats and slacks, while for strong personal preference I don't like ties with BD collars. Currently I wear my BDs and go tieless, but still I'd like to incorporate casual ties in my outfits (knits, wools, linens). Is there anything in beetween dress and casual shirts, spread collared, textured, which would go well with the above sportcoats and slacks? Or should I stop overthinking and use my dress shirts when wearing a casual tie? I feel I'm very well set on shoes so I won't bother you with those as this became a big wall of text quickly. Thanks to anyone willing to go through it and give advice.
