Earlier I finished updating BeWicked costume inventory, and I've just finished rechecking Elegant Moments and Coquette costumes as well! As of right now, everything that is out of stock with them is marked "Out of Stock" on the size line and/or the "Ships Within" availabilty line on the product page.
These 3 manufacturers are your best choice for getting a last minute costume - after checking our costume clearance section for what we have in stock here in our Florida warehouse, of course. BeWicked and Coquette ship from their warehouse in California, Elegant Moments from Pennsylvania. Both BeWicked and Elegant Moments ship directly to you and can be overnighted. Coquette doesn't ship directly, but I can get one of their costumes within 2 days to you - 1 day to me, second to you. (as long as they are in stock of course!) As we are fully authorized dealers for all of them, I have full access to their inventory online and can check it immediately - and will continue to update stock statuses online as they sell out of items. Of course you MUST choose Express Shipping for overnight - standard ground shipping is about 4-7 days (shorter if you are in the state their warehouse is located). Remember Saturday delivery is a LOT more expensive (an additional fee if you state it must be delivered by a Saturday in comments) and will be quoted upon request via FedEx.
None of the manufacturers ship directly international, so orders for outside the US ship first to me, then to its destination, so please allow 3-5 days at least - customs is unpredictable so delivery can be delayed beyond this and is out of our control.
InCharacter Costumes unfortnately does not have their inventory as readily available online and I have to email or call them to find out availabily on a particular style/size. I am marking ones out of stock as I discover them, but they are selling out fast of a lot of styles!
All shoes that are in stock with their manufacturers can also be shipped express and we can check their inventory 24/7.
Please remember that unless an item shows "In stock" meaning it is in our Florida warehouse, items shown on our site are usually in stock with the manufacturer, though they can sell out at any time without notice. I am trying to keep out of stock items marked as quickly as possible. I never charge your card until I verify the costume is available with the manufacturer - anything sold out will be voided and you will get an email about it as soon as possible.
