A question about getting rid of some clothes

I have a bunch of Vintage clothes and an empty bank account and I want to get rid of a bunch of  most of all of my Vintage clothes purchased in the vain hope that a) I would fit into at some point b) I would alter something ugly into something fabulous with some time and sewing or c) I would suit them when I got older... Well none of  those is happening so I'm going to sell every item of vintage that has not been worn in the last twelve months and get rid of it good and Proper, anyways I have about 20 vintage dresses and 10-15 other vintage clothing items between a size 14-32 that need to go and be out of my life soon what would be the best way to get rid of it? a) eBay b) Etsy c) a Big Cartel account or d) here 

all have pros and cons

I'm avoiding the Fatshionista Friday posts as a) i suck at live-journal b) I'm not near my computer all day to answer questions like "what's the circumference of the left arm during a full moon?" within ten minutes of being asked (slight exaggeration there) plus I hate that community on Friday Saturday I ignore it all together on those days. Plus postage from Australia ain't cheap and I hate haggling.

Sigh decisions decisions

My most favouritest dress ever... so far

Dress: Thrush via Etsy
Cardigan: Sara
Leggings: Have no Idea
Boots: Duoboots.co.uk
Necklace: Diva
Belt: evans.co.uk

I love red it's my favourite colour, I love polka dots it's my favourite pattern in fact if I had to style myself on anyone it would be Minnie Mouse

I'm actually amassing quite a collection of baw and polka dot adorned items and have styled the fro to resmemble ears.

This dress is actually amazing I think it's an old plus size beach cover-up from the 70's it's so bright and it's oddly versatile i often wear it blousey and tucked into jeans.
