A shawl is an excellent option as an evening cover-up in the warmer weather; they can be relatively inexpensive so you are able to buy a couple to match various outfits.
Look for glamorous details and luxurious fabrics, either opt for a colour that matches the colour of your outfit or try a contrasting colour, metallics like gold and silver are also great options as they match most colours.
Shawls are also much easier than a jacket to hang over your handbag or hold onto when you aren’t wearing them during the night, they look as good off as they do on.
In winter you can give your shawl a new life by using it as a cosy scarf to brighten up your winter wardrobe.
