Ok! So need two pairs - smart skinnys for wearing with nice tops and heels and comfy ones to wear with flats, previously loved boyfriend ones but can't seem to find them, am size 8 on bottom and 10 on top, am only 5 1, so what styles/colours/shops do you recommend and (stupid question- been long time since bought jeans) do the skinnies get looser as you wear them?
