well, I like to take Paul literally (not literally take Paul, that would be a whole other thread
), so I'm dressing in my white robes 
which, also reminds me of Revelations 7:12-17
"12Saying, Amen: Blessing, and glory, and wisdom, and thanksgiving, and honour, and power, and might, be unto our God for ever and ever. Amen.
13And one of the elders answered, saying unto me, What are these which are arrayed in white robes? and whence came they?
14And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
15Therefore are they before the throne of God, and serve him day and night in his temple: and he that sitteth on the throne shall dwell among them.
16They shall hunger no more, neither thirst any more; neither shall the sun light on them, nor any heat.
17For the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters: and God shall wipe away all tears from their eyes."
of which there is an amazing anthem by Stainer - I call it The Choir Anthem, because we have to wash our surplices before Christmas and Easter services - so we have come out of great tribulation (yes, practising singing is very hard!),and have washed our robes and made them white
