I don't come here very often as I'm neither stylish nor beautiful but I have a holiday coming up and I'm hoping for some help and inspiration.
I'm off to Rome for a special weekend and would like to look my best. My usual attire is gap jeans addidas trainers and a selection of tummy skimming tops mostly bretton, so its not really gonna cut it 
I don't want to deviate too far from what I normally wear but would like to look a bit better presented.
To help you help me, I'm short, slightly tubby, a 12 on a good day, really bad knees and feet so they must be covered and we'll be doing loads of walking.
And just to make things more complicated I'm not uk based so don't have such a huge selections of stores to choose from. Do have Zara, New look, Matalan, a small debenhams & M&S , Esprit and Pull & Bear. Have no time really for internet shopping so hoping for ideas more than anything else on the hope that I might already have them in my wardrobe .
