Fashion accessories are the key to updating your summer wardrobe and injecting some colour into your outfits, according to an expert.Image consultant Julia Cumming, writing for the Buckinghamshire Advertiser, says that having a dated handbag or outmoded shoes can really let you down in the style stakes."Costume jewellery is a great way to keep your look youthful and up-to-date and a bold necklace can give a favourite outfit a new lease of life," Ms Cumming asserts.She adds that you should not be afraid of mixing costume items with real jewellery and suggests that you can choose colours that either contrast or complement the shade of your top.Ms Cumming also recommends that ladies with long necks should wear a choker or multi-strand necklace with long earrings, while those with shorter decolletages are advised to choose longer chains and shorter earrings.Meanwhile, Girls Aloud's stylist Frank Strachan recently told Female First that mixing floral patterns and using fashion accessories to liven up outfits are the keys to summer trends.(c) 2008 Adfero Ltd.
