Many recent fashion trends have pointed to it, and given the popularity of the likes of lingerie as outerwear it should really come as no surprise. Yes, hem lines continually become shorter as time marches on, but Spring 2010 may be the first season where hem lines can be predominantly measured in negative figures.

Once upon a time hot pants were considered more suited to a gymnasium than the streets. But then, in late 2007, the leotard came back into fashion. While it didn't peak on the streets until 2009, and was often worn under skirts, shorts or long furs, in the case of Kate Moss, its prevalence guaranteed that hot pants would indeed be worn by forward thinking fashionisers.
And so there it was on the Spring 2010 catwalks. And again in the front row. Always on the confident personality. Always on a great figure.
Those two latter parts are key to this fashion trend. It is not for the faint of heart, nor those who aren't confident about their figure.

One of the two styles for hot pants in 2010, mid-cut hot pants, start at or just below the belly button. A modern interpretation of the look, it was far less common on the Spring 2010 catwalks though was the style favoured by Miuccia Prada for her Spring 2010 collection.
As it was on the catwalks, so I suspect it shall be on the streets. To balance the fact that a negative hem line is going to reveal a lot of skin high waisted hot pants will be the strongest look for this trend in 2010.
For those who have enjoyed the vintage revival of recent years have, a vintage interpretation of hot pants is definitely on the cards. To achieve a vintage look invest in a good pair of high-waisted hot pants. When wearing them, look to the classic pin-up girl for inspiration. In particular, draw on the girly motifs that are evident in most pictures of vintage hot pants; nautical detailing is a prime example (just don't take it to the level of being a parody) though a fusion of hot pants and lingerie as outerwear is the most predominant for Spring 2010.

If hot pants don't take your fancy the consider boy shorts an alternative. Taking their inspiration from boy shorts knickers the cut is akin to hot pants, though differentiated by a featuring a hemline that doesn't curve up the body. Think of short shorts, just not in denim and without the rips, and you're on the money.

If you want to invest in the boy shorts as outerwear fashion trend then ensure that you're wearing a pair that have these two features:
Boy shorts and short shorts featured in a number of Spring 2010 collections. Notably:

For those days when you're not feeling up to the bum-hugging look of boy shorts or hot pants, consider instead loose boy shorts / tap pants. More a part of the lingerie as outerwear fashion trend than the hot pants fashion trend, loose boy shorts in 2010 should pair flowing shorts with, preferably, lace or semi-sheer material.

Over the past years body suits have come to represent a basic item; not a basic in the sense that everyone has been wearing them, but in the sense that they've primarily been worn in basic colours and styles. That's meant that fashionisers could take the focus off the body suits themselves and use them as a blank canvas to be paired with statement accessories and eye-grabbing layers.
Spring 2010 will see that change. Yes, bodysuits will still be used with layers, but they'll become the statement pieces themselves. Francesco Scognamiglio's Spring 2010 catwalk made best use of this interpretation of the look, infusing the Grecian fashion trend into two body suits (both below). Rochas Spring 2010 collection also featured body suits, but these were in knit fabrics somewhat reminiscent of vintage bathing suits.

While analysing this trend two things became clear: #1 the distinction between the styles of hot pants, short shorts, and boy shorts wasn't in the least bit clear, #2 that this was as a result of the fact that public taste has largely changed. As you peruse the pictures above and those in the inspiration gallery below you'll realise that what counted as hot pants the last time they were a trend would now be considered a short short (at most). As such, for 2010 a redefinition of the styles is needed:
Hot Pants
Boy Shorts and Short Shorts
Tap Pants
Body suits
