Less clothes = the need for better shapes

The reality is that when it is hot, the best idea is to keep things really simple.  The problem with simple is that without a little care and due attention it becomes boring, really boring.  So let's discuss options through shapes and fabric.  Most people have a selection of clothes appropriate to hot weather holidays but have no idea how to translate those into a work outfit that doesn't look either too casual or a little bit silly.  The reality is you can't stroll into a work environment in a t-shirt and some shorts that you'd wear to a BBQ, but you could wear these...
and still look professional.  By choosing items in higher grade fabrics, you have more options, instead of the summer staple of linen, consider silk, which isn't going to offer the same problems of stretching out of shape and creasing that linen can and does.  A few of my clients express the opinion I may have lost the plot when I suggest shorts for the office but actually they are a lot smarter than some of the skirts I see on the train in the morning and more demure too.  As an alternative go for a crop trouser, you'll be amazed at the difference it makes to your comfort level and they look damn good too.

So on to that t-shirt, instead of the block colour, box option which is really only appropriate for the gym, from now on.  Let's consider some more interesting items that accomplish the same job but in a much better and more attractive way.
By choosing colour and focusing on shape you can achieve an outfit look with far fewer pieces, if the clothes are more interesting they don't need to be upgraded through accessories.  You have the option to throw them on and run out of the door, looking cool and stylish in a relaxed and easy way, without feeling as Southern Belle as wearing a dress can sometimes lead to.
