Sorry I know there are endless threads re ankle boots and skinnies but I've never seen one address this particular dilemma!
I am quite tall and whilst I am careful to buy only longer leg length jeans I do have a few pairs that are just long enough. I have some ankle boots from Zara into which all my jeans disappear neatly but have some h by Hudson encke boots and some ash Beas where some jeans just sit on top of the shoe... weighing things up the boots are a crucial inch shorter and also cut wider. I tend to wear bright socks - not as a fashion statement but because there are five of us and it makes it much easier to separate out the socks if mine don't blend into the black and grey school uniform pile. However this can result in hideous flashes of purple or red marring my outfits. Thinking about it on shots of models wearing ankle boots and shorter jeans there is never any sock visible, particularly not anything loud.
Assume on photo shoots they might overcome this problem by not wearing socks but not really an option in real life in the snow! So just wondering what do other people do?
