Purse colours should coordinate with your shoe colour. A good purse should be small, but easy to open in case you need to find an item inside.
2. BRIEFCASE AND PORTFOLIO
Portfolios are preferred over briefcases and should be padded in a neutral colour. If you take a briefcase, it should be as small as is practical for your needs and made of leather in a neutral colour.
It is fine to wear tasteful scarves in the office; just make sure they are accessory scarves and not winter wear. Tie your scarf in an infinity knot or go with a simple knot — resist the urge to be trendy and tuck it into your belt.
Choose colours that complement your overall look and not that compete with it. If you wear a chunky scarf, size down your jewellery (and skip wearing a necklace).
Earrings should be conservative and small. Necklaces should not dangle between cleavage, and bracelets should not make noise. Do not wear ankle bracelets, but do wear a conservative watch.
