Stripes, prints and black-

So I'm absolutely LOVING the striped maxi dress in this picture- but please be carefull trying to copy this look. Horizontal stripes tend to make one appear bigger/ wider than we actually are. Similar maxi dresses in similar fabric was seen at Jay Jays.
Now the leopard print- If you had asked me 2 years ago about leopard print, I would tell you it belongs on a leopard and nowhere else, but 'here we are and leopard print has made its appearance'. Although I prefer leopard prints on a neo colour background, instead of the natural tan colour, certain garments; this skirt, looks good in the natural leopard print.
Heel are an absolute stunner...but that's because I bought a pair similar to it.
How to pull these looks off...?
