Easy tips to put together casual party outfits

1. Combine casual and formal

The key to the success of many outfits, no matter what the occasion, is combining formal elements with some casual clothes or accessories.

3. Choose luxury fabrics for your casual party outfits

You can still wear your jeans for a party, but how about choosing a velvet pair, for example. You could also opt for a leather skirt and wear it with a cashmere, silk or satin top.

Casual party outfits – 9 outfit ideas

Let’s take a look at some specific outfits you can put together for a house party or an informal gathering.

Party wear: Jeans and a nice top

You really can’t go wrong with jeans and a nice top for your party. You can add a more formal touch to your outfit by choosing a top with an interesting neckline or silky material, adding a statement necklace and wearing with small heels or metallic flats. If you are attending a more casual lunch, you could wear with on-trend booties.

sweater and wide legged pants

Wearing a sweater with a pair of palazzo or wide pants is another good way to mix formal and informal. Style with sneakers to ensure you don’t look too dressed up or wear with heels for a dressier look. A pair of metallic jeans will get you noticed for the right reasons.

If you like to wear jeans to your parties, how about treating yourself to an on-trend pair to update your outfits. Look out for jeans with embellished details, patchwork or step hems. Wear with a blazer and heels to get a good balance between formal and casual. Or team with sequins and a cozy cardigan.
