This is very pretty. If you can, buy a petticoat to fill it out for the most glam look. I ordered a size larger than needed because it was a halloweem costume and I wanted it to fit over dd's clothes for trick & treating. However,the sizing is very accurate and it has a stretchy bodice so you should be ok with the regular size. I have 4 kids and have had many costumes come through the mail and this ranks as the all- time- best made one that I have ever purchased. I will def purchase from this company again. Top Notch!!
