First things first; run, don’t walk to the size chart! It is essential that you take a look at the size chart for each item you are interested in. Even within the same retailer, there can be sizing differences between styles. To make sure the dress will work for you, take your measurements. If you feel uncomfortable taking your measurements- that is okay! Grab a dress that you love, and that fits in a way you like. Take measurements of that garment and go from there.
