First of all, you need to look at your figure. If you are too skinny, you cannot wear something that is too loose. This is because the dress would hang from different places. The fall of the gown should be such that it should lightly cling and not stick to the body in any manner. If you are not skinny or you are of average weight and built, you can keep the gown tight in certain areas. An example can be the hips and waist. The gown has to be designed according to the body structure. Those who are plus size should be careful when selecting their evening gowns because most of them are designed for people with perfect figure. If you have heavy buttocks then you should consider a gown that has more fall and frills on the lower part, as this design camouflages the large behinds. Ladies in their middle ages who develop large bellies should consider evening gowns that are short and the strapless as this design looks very appropriate on this kind of figure.
