They are a huge trend for this spring/summer 2013 and they are not going anywhere in a hurry.
I do agree that dungarees in particular are not for everyone and they most definitely have an age limit depending on the style chosen and how they are styled.
I have been browsing the web for some star buys in relation to both dungarees and pinafore dresses and where else could be better to search then the two high street giants that everyone loves TOPSHOP and URBAN OUTFITTERS.
Here are my top picks from both sites:
Great for the summer. Id say that this type would suit women up until their 30's.
The long trouser dungarees are that bit more difficult to pull off, it all depends on what way you style it. If you want simple, I would recommend a plain shirt or top but if you are daring and are body confident pair these dungarees with a crop top and some killer platforms or even flatforms!
These khaki ones are really different and are great for most ages as this khaki green colour is really flattering. 
Yet again Topshop never cease to amaze and to produce such stand out clothing. This pattern is so fashion forward but I do think that these ones are more suiting for the more youthful girls. I really love them with the white heels in the photo here.
A playsuit type dungaree, really great for all those legs elevens out there!
Really elegant urban outfitters dungarees suits a wide range of ages.
These black ones can be worn casually during the daytime with flatforms, loafers or a great pair of boots and it all depends on your age on what you wish to wear underneath. To dress up for the night, switch your flats for those heels and accessorize to the max to make a real statement!
Another great one from urban outfitters.
Yet again classy and elegant, another one to suit both the younger and more mature age groups.
Due to the texture and colour I think that these short dungarees would suit both women up into their 30's, 20's and of course teenagers. These are a wardrobe staple.
Dotty monochrome pinafore dress. what is not to love? This screams youth, summer, fun and festivals!
Alexa Chung comes straight to mind when I look at this outfit. So stylish and so if you admire the fashion icon that is the beautiful Alexa Chung you can pull off her style with this timeless black pinafore.
Really grunge and effortless. Summer is here!
My favourite find from Topshop! The colour aqua is so energetic and fresh, these can be dressed up or down and I think that they would look amazing with really thick white platform wedges with a big floppy hat and a great pair of big round sunglasses.
So whether you are in your teens or your thirties you can find both dungarees and pinafore dresses to suit your age and your own personal style.
