Cocktail parties are the great occasion for the renowned small black dress. Anything your clothing, keep it elegant and dressy, but not too official.Think about the invitation. If it comes by e-mail or phone, prospects are it's a more casual event. If you got a formal invitation, and particularly if the event benefits a association or charity, think it a dressier affair.

Pick skirt and dress length from mini to only above the ankles. Keep anything like a full-length sequined dress for a special occasion.

Select fabric which matches to the season. Wool and wool mix are perfect for winter and fall; satin, rayon, silk and fine-gauge knit is a great for the summer and spring months.

These fabrics can be dressed up or down with handbags, jewelry, shoes, hairstyles and wraps.

Attend other formal party after-work in a business outfit, or if you dress in more casual dress to work, carry an outfit to alter into. A black wool clothes with pumps and stockings is a easy solution for winter or fall. Pair a spaghetti-strap or strapless dress with an embellished cardigan and strappy sandals or slingback pumps for a summer or spring event.

Wear a wool skirt with a fitted leather and turtleneck flats for parties in winter. Consider a fine-knit twinset, low-heeled mules and slim satin pants in the summer.

Carry a printed A-line sundress to a cocktail party on weekends. A party planned for a weekend evening affirms a more flirty or elegant together. Pair a silk empire-waist or colorful satin dress with a silk or velvet shoulder wrap.
