Putting on black attire is a perfectly buttoned-up bet in an attempt to attain an elegant style. Either you are planning to wear a formal suit, dress pants, or a cocktail dress, if in doubt; buy it in BLACK.
Note: You can think of the other formal colors as well.
Avoid anything too low cut
In an attempt to dress sophisticated and classy, make sure not to put on any apparel that shows a lot of your cleavage. It is always safe and better to go for understated style of clothing rather than something ostentatious that will be showing a lot of your skin. Men should also avoid low cut as it leaves an over all rough look.
Keep away from too short dresses
To dress really classy and elegant, you seriously have to bend forward towards the side of more “conservative.” But, it does not mean that you need to be dressed in a too long moo-moo or to cover yourself very tightly. Neither expose too much of your body parts nor wrap yourself. Just be sure that you are going to be at ease with the amount of body parts you show.
Wear simple and stylish pieces of jewelry
In order to look perfectly classy in your selected dress style, try to wear well-designed jewelry / accessories that compliments your clothing without devastating your overall look. Women can wear an elegant pendent, earrings and a bracelet. While, men can put on a tie clip, cuff links and a wrist watch etc. Make sure not to wear gobs of jewelry or the gobs.
Note: Few selective pieces of jewelry are enough. So, do not wear too much jewelry.
Carry yourself with confidence
Your dream to look rock others with sophisticated and classy dressing will remain incomplete until you carry yourself with self-confidence. It's all about you; believe in yourself, believe in your clothing choice and rule the world of elegance and style.
