Just one word:
DON'T
If you are really overcome with guilt, or shame, or whatever emotion causes you to want to purge your femme stuff, instead of throwing it all out, try this instead.
Buy a few of those large rubbermaid tubs, enough to store your girl things in.
Pack your stuff carefully. Use separate large ziplock bags for jewelry, cosmetics, breast forms, and wigs. Put like items in the same tub, dresses in one, blouses and skirts in another, etc.
Then, find a Self Storage place. They usually have a variety of sized storage options, some are just like closets, and store your things there.
Purging is only a temporary solution, and a costly one, on both the financial, and emotional level.
That beautiful gown? Those fabulous heels that you love? You might NEVER find them again due to changing styles and inventories. And the monetary cost! Do a rough calculation on what it cost to build up your wardrobe. Do you have the resources to spend another 2, 3, or 5 hundred dollars to replace it all?
I have purged, several times in the past, and regretted it every single time.
Trust me on this. The monthly cost of a rental storage unit is far less costly than purging.
