you only have enough time to buy the dress from the rack. If you order it, it will take at least 8 weeks no matter which store- so you are runnin gout of time. to buy the dress from rack, DB is the best- they are in good condition and lots of basic styles ( not fancy). You might be lucky to find one fitting you well on waist and chest. but normally you need to hem the length a little. hemming is very easy, it can be done within one week at any shop.
