http://www.corset-story.com/Corset Story is where I purchased the corsets I was wearing this weekend. My models were from the waist training section, for the extra stability and heavy dutiness, but they do have "fashion corsets" (less rigid, acrylic bones rather than steel) as well. I highly reccomend checking out their "Corset of the Day" section, which changes every few days, as well as the "sale" area. Both the purple and the black corsets I was wearing ran me about $60 each, and are worth every penny. For anyone long-waisted or over 5'6" in height, I strongly reccomend looking for a "long line" corset, because the regular length ones will threaten a boobalanche to the taller girls. It's pretty easy to hit the "free shipping" threshold, but be prepared to pay duty on your order when it arrives to you from the UK.
http://stores.ebay.com/roses-deluxFor those on a more restricted budget, I've also purchased a few items from this ebay vendor. These are a fashion corset line - while less expensive, they are also less heavy duty, and have acrylic boning also - you will likely still want to wear a support garment with these if you are well endowed. Many of the items run at around $20, many have free shipping, and I was not required to pay duty because of the method by which they ship from Hong Kong.
http://stores.renstore.comI have a TON of stuff from RenStore, including some of their ladies' bodices, and Zelina's standby red ghawazee coat. While their bodices are not really structural, their stuff is sturdy as hell. I highly recommend them for both the ladies and the gents, as they've got surcoats and doublets and pants and skirts suitable for a number of different concepts. They have some belly dance gear, and childrens gear, for those who dance or do faires with the whole family. All my tapestry-curtains are from Renstore as well.
http://www.garbtheworld.com/I have purchased a couple items from GTW, primarily for renfaires where I need something sturdy in specific colours. They can take a while to come in, but they have way more customizable stuff than other vendors. They've introduced a bunch of new stuff since I last ordered there. Recommend you take a look!
http://www.houseofandar.com/This is where I got my wicked awesome boots. Jordan has a set as well. Varying heights, hiking soles, very sturdy and super in-genre. Can't be beat!
