The shape of a trumpet wedding dress is fitted through the bodice and hips with a flair at the knee. Today we're discussing Mermaid Wedding dresses. This dress I have is a mermaid/trumpet wedding dresses. The trumpet or mermaid wedding dresses fits nicely through the bodice, fitted through the hips and then flare at the knee. These dresses are pretty difficult to pull off. If you have a very curvier figure you can definitely accentuate your curves with dresses of this style. If you are a little bit fuller in your figure, this dress doesn't quite suit you the best. If you are a slimmer figure and have a little bit of hip you can also have the seamstress take it in a little bit so that you do have the illusion or style of a mermaid dress.
