I've put on weight over the lockdown and got into the habit of wearing comfy clothes to Wfh. None of my smart stuff fits any more, I'm due to attend a funeral soon but just have no idea what to wear. Must be black or dark grey, very traditional. I've been looking for a dress but I'd want a pretty long one as I'm tall and a knee length dress ends up being too short. I can't find anything that is smart enough, long enough etc. please help!
