If you're not into scarves but you're looking for something to add interest to your basic outfit, how about wearing a statement necklace or some attractive arm candy (I'm talking bracelets here, in case you're deliberately misunderstanding me!)
Using the same basic outfits as shown in my previous post, I have added some necklaces and bangles to illustrate what I mean. Please note though that I'm not suggesting wearing a statement necklace and a bangle at the same time, especially if you're a petite. If you prefer ear-rings to necklaces, you might like to add an interesting pair that either blends with or contrasts with your bracelet, which could be a flattering look if you need more colour near your face.
As I've pointed out before, wearing shoes that are a similar colour to your trousers is particularly helpful for petites, as it helps to draw the eye down and give the illusion that you are a bit taller. On the other hand I'm not know for sticking to fashion guidelines - and I might very well be tempted to wear a pair of red shoes with a red necklace or bracelet, just because I love a pop of red!
I'm very much aware that some of my over 60 readers may have retired and not have the disposable income that they enjoyed while working. If you click on the following link, you will be able to see the items that I have chosen from Polyvore when creating the above collage. Only two of the necklaces and one bangle cost over 100€, which I hope demonstrates that it is possible to create interesting outfits even when you're on a limited budget. The other pieces of jewellery shown are from cheaper stores like Forever 21.
