Oh, I know, so simple why am I asking? I'm just no good at putting a 'look' together. I need something to go with straight navy jeans - thinking converse for feet but what on top to do the effortless trendy casual look. I've tried them with a boyfriend cardigan and stripy long-sleeved t but the cardigan makes me look really dumpy 
. So I suppose a shorter or cropped cardigan with the t peeping out the bottom would be best. I'm stuck on colours though - bright colours feel too bright, neutral too dowdy. Can anyone suggest some top half combos please - and if anyone as the time or inclination, scarf or necklace accessories to finish the outfit off would be the icing on the cake!
Thanks
