The world of lingerie is fast becoming one of the biggest parts of the entire fashion industry. Even just about fifty years ago, no one would have thought that crowds of men and women would assemble to watch sexy models marching down in hottest bras and panties. The models that walk down the isle to show off the latest trends in lingerie have become quite trendy in the last few years. Names such as Tyra Banks, Gisele Bündchen, Naomi Campbell, Laetitia Casta, Eva Herzigova and Heidi Klum are recognized all over the world.
Lingerie is a huge industry and a lot goes on in the ever-changing and exciting world of women's underwear. For fashion lingerie modeling, the body needs to be perfectly toned and well-shaped. Becoming a model is basically the same for all categories, however, it is just about choosing your area of interest i.e. whether you would want to be a garment model, or a swimsuit or lingerie model. You would have to contact the right agency for the specific interest. 
It requires a lot of hard work to initiate your career since it is a very upcoming and therefore competitive field. To make your stand in the industry, it may take a lot of time but hard work eventually shows its colors. It's just about the right eye to spot you on that ramp where you walk.
The endorsements also give you a lot of popularity. Companies like Victoria Secret that are famous all over the world for their lingerie, are also famous for their models that endorse their products so well. The salaries are hugely variable as prestigious companies can pay excessively high, whereas others may just cover your costs. A specific figure is difficult to state but since this career does not last very long due to age factor, it pressurizes the models to work as much as they can in a short time. The top models work harder for their career and money.
