Here are my top fifteen picks for plus size Halloween Costumes. To make it into my top list the costume had to have a size variance making it an actual plus size; meaning, not Queen size which in my opinion is not really plus size although many costume companies would like us to believe it. Another stipulation was the costume could be sexy but not raunchy. I also did not pick things on clearance because I wanted to make sure there was more than one or two available.
You will notice that the primary choices are: Goddess / Queen, Story Book, Vampire, Pirate / Wench, and Alternative (not a standard). If you want something truly unique and in your size I recommend you take up sewing, or find a friend who does!
Here are my choices and the top three places to get them and the prices at each but do not only consider the price, consider the items included in the kit, the cost of extras, and the the shipping costs to your area. Also please note that the prices change constantly and sites like Buy Costumes have discount coupons often located within the site.
