Fortunately for me I am a clothes horder.  I love clothes and I would never get rid of any because I would always tell my self "I will fit into them someday".  I had my surgery on on 10/30/13.  I am down 45 pounds and and into a size 14-16.  I already have a huge stack of clothes to donate that are now to big.  I will not horde them!!  I will never fit in that size again!!  It's happening so fast, thrift stores here I come!!  I did buy a few medium tops with a gift card that I got for christmas, hoping by next summer they fit, but don't go over board with buying new stuff you will just be disappointed when its time to get rid of it.  It will be sooner than you think!!

You are not crazy for dreaming of pretty clothes. I am doing the same thing. At Xmas my FMIL gave me XL shirts with the expectation that I would shrink into them.

I WOULD treat myself to some new clothes (I am sewing some Vogue waiting for the day when my hips are 50.5 inches).

My only worry is that they are seasonal clothes and that you may be TOO THIN for them when it comes time to wear them again.

Maybe buy a large instead of an XL if you must have them?

Take care and keep fighting the good fight!
