Transitioning from day to evening

[Tobus]

To quote WARPIPER: "Dress is dark jacket and tie. Kilts are encouraged." Since it starts after 6 PM, my take on that is dark suit-equivalent but not black tie, hence the nearest thing I came up with was a black argyll jacket and waistcoat.

Ah, OK.

I'm assuming you've seen this thread? Steve had a pretty decent and straightforward set of guidelines on the difference between day sporrans and formal sporrans.

OC Richard also posted this thread with examples from a 1920s vintage catalog of sporran types and their uses.

There are a lot of hybrid type sporrans which claim to be "semiformal" but seem really out of place for both day dress and evening dress. I do think that informal evening dress calls for something that's a step up from a day sporran (i.e. not just leather), but should stop well short of being the type of sporran one would wear with black tie (i.e. metal cantle with fur). Richard's post #4 in that thread has some interesting examples for perusal.

After looking at his post, I've narrowed my options down to two, then. First, the ones I currently own are similar to the following.
Daywear:

Evening/formal:

Since neither of those two were deemed appropriate, what about one of these, from J. Higgins, that are in my price range:

IMO, swapping sporrans is a good idea. Yet, as I have done in the past, a good "but, dear, I NEED this sporran for this event" can be of some value later If purchasing for the occasion, I'd go for the semi-dress budget. From a practicality perspective, it can bridge the day/evening nicely and is sufficiently different from what you already have that it could expand your range of choice in future.

Female perspective:
-Change your shirt eg: blue or tattersall at the office> clean, pressed, fresh white at the event.
-As long as your sporran is tidy and polished it should be fine but if you can afford a new one why not?
-Women change handbags all athe time from day to evening, it’s a simple change over.
- take a shoe kit and give your footwear a once over (same with the sporran if not changing)
- add a pocket square in the evening.
- add a sgian dubh or a dressier one (if allowable and appropriate)

I think little touches like cleaned polished shoes and a pocket square lift your attire from office to evening .
