Style ideas for 5'3 size 10

[gateacre1]

My wardrobe needs revamping
I am size10 (can fit into vanity sizing shops 8)
I have hips and thighs (obviously but am curvy)

I would like to try skinny jeans but feel like I look a bit triangular on my bottom half iykwim
I can't stand heels so outfits need to look ok with ballet flats
And I hate tight clothing that is uncomfortable

Any ideas? Or any shops I could try ?
I mostly wear white company stuff and Isabella Oliver or sweaty Betty stuff
What I would like is to look a bit more stylish

Any tips gratefully received

I'd suggest trying a personal shopper at John Lewis or Debenhams - or splash out at Selfridges or Liberty - to try new clothes/styles/colours. Once you have an idea of colours/styles/cuts that suit you'll find it easy to put them together yourself.
