Ok, so the title says it all really.
I have a very frumpy all same length haircut which falls about 2" below my shoulders. I'm desperate for a change and would really love something a bit more up-to-date.
I'm mid-thirties and my hair colour is brown.
I have a two main problems though (there are many more but I'll keep it to the main ones 
)
The main one, is that I'm overweight (am working on this) and am size 18.
I have a very round face.
I have been told to stay away from short cuts because they won't suit the shape of my face (friends have told me this btw, I haven't asked the hairdresser yet), so short cuts are seemingly out
The second one is that I have young children who are reliant on me getting them ready in the morning, so I have very little time in a morning to be styling it.
I would love to go for something short and trendy, but failing that, something at least a bit more current.
Any ideas what suits a mid-thirties, roundfaced, haggered mum?
Pleeeeeeease ...
