Attending my mom's barbecue birthday party today. Rocking a navy wool blazer with MOP buttons, sky blue cutaway shirt, cream chinos, white linen PS, cream/navy silk tie, mahogany full brogue oxfords and same socks.
Is the fit of the jacket okay? White PS may look a little off here, but unfortunately hadn't had access to my full wardrobe. I'd rather go sockless with dark brown calfskin loafers or tan shoes and cream socks, too. Nonetheless, here is the fit:
Socklessness is the work of Satan. Your shoes and socks are both appropriate and magnificent.
I'd suggest a warmer-coloured tie, or even just the PS as you suggested, but the overall effect is most respectable and considered. Nice work!
