yeah, i have a huge amount of outfits on flickr now, from the WAYWT thread and I find it quite useful to see what worked with what. It also reminds me of stuff that i have that i forget about. Now I think I will tag them and organise into seasons, so I can go through and find both items and outfits.
But I rotate and store my wardrobe seasonally due to space constraints and when i do this, i do a cull and a mental inventory. I still forget though and discovered that I already have two pairs of wide tweedy trousers, after I had bought some new season ones.
Some of my friends think its odd to post pics and take pics of clothes but its really useful. anal, but very useful . . .
