mine don't go out all frily, or tarty either, and I have 3 girlies of 9, 12 and nearly 14! (and all are tiny ballet dancer figures so all still in kiddie sizes!)
I get many of their clothers from....
new look for their jeans, or the sophie range from mark one
primark for tops and jumpers
peacocks for any and all
undies from new look, m&s, tesco, H&M, gap, sainsburys, asda (I need lots of choice as I get one set per shop per girl to ensure less mix-up)
tesco for any and all
some from GAP, but normally sale stuff
I find that, in all honesty, they are all suiting different styles, so I need bits and peices from different places.
DD1 is more trendy, but then she is almost 14 and needing to keep up with her peers
DD2 is hippy/chic at the moment, so bagg jeans and loose tops the prder of the day!
DD3 is all girly and sparkly and fluffy, so she is rather easy right now, but maybe in another year will be harder....ooh, I like pumpkin patch for her....she is them thro and thro!
