I am not europrep - but I do wear chukkas up to the sport coat / tie level for formality (assuming the design elements of the chukkas in question are appropriate to such a pairing).
Thanks @RogerP and @Chawk806
I've never been a chukka fan but both G&G Aaran and AS Radwell have a certain appeal to me. Perhaps due to their level formality. For a chukka anyway...

The Arran is on my must-have list.
These are Arrans (not mine, regrettably).
