Thank you for the feedback regarding this dress CD943 by Cinderella Divine. It may be the case that this particular style runs slightly on the larger size. Since this dress is stretchy, it is good to know that the dress runs slightly larger.
Normally, I recommend to all my customers that when choosing a size, to look at the size chart located near the description of each dress and base your decision by your waist measurement. This is important because if you cannot zip the dress past your waist, then you won't be able to zip the top up. Each dress has a specific sizing chart. Therefore it's important to look at the sizing chart for each dress. If you're not sure, let me know your bust and waist size and I can recommend a size for you. Lastly, in most cases, slight alterations for a perfect fit may be required by a local seamstress in your area.
