Be it your first Job or 10th… apart from your skill and intelligence even your appearance plays an equal or in some job profiles, even more important role. Here are some guidelines for you to dress up perfect to just bag that job;
If you would wear it to a club, you probably shouldn't wear it in a business environment.
Tailored pants suits are appropriate for women. Pants suits can be an excellent choice for site visits, particularly if the visit involves getting in and out of vehicles and/or the site is (or includes) a manufacturing plant or industrial facility. If you wear pants, they should be creased and tailored, not tight or flowing. If you are pursuing a conservative industry and are in doubt, observe well dressed women in your industry on the job, at career fairs, at information sessions, etc.
Much of what you see on television shows that masquerades for professional attire is actually inappropriate for a work environment. Your skirt should cover your thighs when you are seated. Showing a lot of thigh makes you look naive at best, foolish at worst. A skirt that ends at the knee when you're standing looks chic and professional. Longer skirts are professional too; just make sure they are narrow enough not to be billowing, but not so narrow that you can't climb stairs comfortably. Don't purchase a skirt or decide on a hem length until you sit in the skirt facing a mirror. That's what your interviewer will see. Ask yourself whether it will be distracting or reinforce your image as a person who looks appropriate for a business environment or gathering. High slits in skirts are not appropriate. A small back, center slit in a knee-length skirt is appropriate. On a calf length skirt, a slit to the knee to facilitate walking and stair climbing is appropriate.
Navy, dark gray, brown and black are safe. Other color trends may come and go; avoid the extremes. Women generally have more options with suit color than men. For example, while a women could look conservative in a slate blue or light gray suit, these colors would be inappropriate for men. Choose a solid or very subtle weave pattern or plaid (the type that looks solid across a room). Wool, wool blends, and high quality blends and synthetics are appropriate for women's suiting.
Underneath the suit jacket, wear a tailored blouse in a color or small print that coordinates nicely with your suit. A fine gauge, good quality knit shell is also appropriate underneath your suit jacket. Don't show cleavage. (Remember that television shows are trying to attract viewers, and don't represent reality of the professional environment.)
Wear a conservative watch. Jewelry and scarf styles come and go. Keep your choices simple and leaning toward conservative. Avoid extremes of style and color. If your industry is creative, you may have more flexibility than someone pursuing a conservative industry.
Keep makeup conservative. A little is usually better than none for a polished look. Nails should be clean and well groomed. Avoid extremes of nail length and polish color, especially in conservative industries.
Should be leather or fabric / micro fiber. Shoe styles and heel heights come and go. Choose closed-toe pumps. Regardless of what is in style, avoid extremes; no stilettos or chunky platforms. Make certain you can walk comfortably in your shoes; hobbling in uncomfortable shoes does not convey a professional appearance.
If you carry a purse, keep it small and simple, especially if you also carry a briefcase. Purse color should coordinate with your shoes. You may choose to carry a small briefcase or business-like tote bag in place of a purse. Leather is the best choice for briefcases; micro fiber or fine woven are also acceptable. Avoid purses that look like beach/pool totes, partyish, or little-girlish.
Even if you wear a plain churidaar or for that matter a sari, do not forget to carry it confident. Rest all would follow you and you yourself can witness the difference your confidence has made on yourself…
