Slips are traditionally worn as undergarments and can cover the upper and lower body or just the lower body. They’re worn for reasons including extra warmth, protecting the skin and preventing other undergarments from showing through a dress.
Slip dresses, on the other hand, are essentially slips designed to be worn as outerwear. They became popular in the early '90s and carry many of the same traits, such as being thin, commonly made of satin and using spaghetti straps.
If you’re wondering how to tell the difference between a slip and a slip dress due to their nigh identical looks and designs, you aren’t alone. But the answer doesn’t depend on the material — it depends on you.
If for some reason it’s too uncomfortable for you to wear only it out and about, use it as underwear. If you feel comfortable in it, then throw on some accessories, dress it up or down with your shoes, and go have fun.
Slip dresses come in every length from the upper thigh to the ankles, but they most commonly end in the mid-thigh, around the knees or between the mid-shin and the ankles. Shorter lengths are more youthful and better for parties, while longer lengths are more elegant and better for classier events.
Some slip dresses have a slit up one side or, on rare occasions, up both sides. They’re more common in longer dresses, though a handful of thigh-length dresses also have them. These make it much easier to walk, though they may show more leg than you’re comfortable with.
The typical slip dress neckline is either straight or has a slight curve to it, and is around the upper chest. You can also find V and low-cut necklines.
Traditionally, slip dresses are solid colors, with the most common being white, black and beige as a throwback to their undergarment origins. Now, however, you can find them in essentially any color, whether muted or a vibrant jewel tone. Occasionally you can find them in patterns, most often floral.
Lace and slips have a long history together, so it’s only right that many slip dresses incorporate lace. The usual places to find lace are around the neckline and across the bottom hem, whether in both locations or only one.
Non-brand-name slip dresses typically cost $10-$50, depending on the designer or seller. Brand-name slip dresses can cost several hundred or even several thousand dollars.
