i'll be attending a 50th wedding anniversary celebration for family friends (not direct family) in october and would appreciate some help finishing off my ensemble. it is an afternoon dinner which i expect to be informal (not casual).

for sure:
ferguson modern kilt (pictured below)
white long sleeved shirt
plain black jacket (blazer tailored to kilt length)
black dress shoes (pictured below)

unsure of color hose and type of tie.

the hose i have all match the kilt: navy, forest green or hand mades pictured below.

the ties i have are black necktie, ferguson modern necktie or black bowtie. i'm open to purchasing new tie.

WOULD APPRECIATE FEEDBACK ON HOSE AND TIE.

thanks in advance.
