Test the most active situation first
If you will play with children or help set up, bend and squat. Check whether the waistband stays comfortable and whether the top moves as you want. A long pendant or loose bow may get in the way. Remove those details if they serve no purpose for what you will do.
A skirt can work for these movements when its length and width suit them. Trousers are comfortable only if they allow enough room when bending too. Decide from the actual fitting rather than assuming one type of garment is inherently more flexible.
Think ahead to the dining table
Fasten or arrange sleeves so they do not hang over plates and glasses when you reach. A soft top with a defined cuff may be easier here than very wide, long sleeves. If you prepare food, add delicate extra layers afterwards where the schedule allows.
For a longer seated period, test the exact underwear and belt you intend to wear. Several small pressure points become more noticeable together. Changing how you wear the top may help without replacing the whole outfit.
A spare piece with a clear purpose
If spilled drinks or a longer outdoor period seem likely, a spare top can make sense. It should work with the same trousers or skirt. A complete second combination takes considerably more room and is needed only when the occasion calls for it.
Consider household arrangements, such as whether outdoor shoes are removed. Choose socks or other suitable indoor options deliberately too. A combination that depends on a particular heel may leave trousers too long without shoes. Test that version beforehand if you will actually wear it during the celebration.
