Help Me with the Seasonal Clothing Switch!

Is there any way to simplify this task for a family of 6? I am bombarded by clothes! My boys continue to wear shorts and t-shirts around the house all through the winter (no, my thermostat is not too high-I usually am wearing a scarf). Point being-I don't put those away.

I try to purge but I'm still overwhelmed. I'm giving myself a deadline, here. The kids are anxious to bust out Halloween but I refuse until the regular clothing switch is finished. Any tips are greatly appreciated!

No posting on this blog-I haven't been actively simplifying.
