I'm going with my partner this Friday to a charity event, golf during the day followed by a charity dinner and auction on the evening. The information given says the dinner dress code is smart/casual - what do I wear to this!!!! I've only been to a few similar events and I've just worn a nice dressy dress! It's forecast 28c aswell. Would this be unsuitable? Any tips on what to wear would be greatly appreciated, I won't know anyone other than my partner and am already nervous 😬. Thank you.
