am feeling decidedly fat, old, knackered and frumpy thanks to a 3yr old and a 5mo old and having a crisis. am neither stylish nor beautiful. have gone from a size 16 pre preg and now somewhere between a 12 (top) and 14 (bottom) so nothing seems to fit properly. am slowly trying to revamp my wardrobe a bit at a time and so far bought a pair of gap long and lean jeans which actually fit. however i have no idea what i should be wearing on my feet now that its geting colder. in the summer i live in birkenstocks , and pre mat leave liked heels for work but not practical now carrying dd in her sling. so what should i go for? any ideas most welcome. and in general what few key items would you suggest i get to start feeling lovely again?
