The perfect outfit to wear when you go and pick up your family or friends from the airport.
A great way to welcome travellers who have been confined in an airplane for more than 10 hours, who are feeling tired, dirty, and in a state of excitment (because this is the end of the journey, they are going to see you again after a long time), relief (they know they can rest and have a long hot shower) and slight worry (are you going to be there to pick them up?).
Of course, they will have no idea that you will have put on your Sunday best. Your visitors may feel inadequate facing such a degree of good taste, but be reassured, they are more likely to go into cardiac arrest when they finally realise who is parading incognito in front of them…
