Meghan has stuck predominantly to neutral shades for her royal engagements to date - with green being the only other colour she's worn.
And now, experts have revealed that her favourite colour may be helping to give her a 'feeling of safety and reassurance' according to DailyMail.
Prince Harry's fiancée, 36, has been favouring a warm forest green shade in particular, which could be a sign she is feeling 'apprehensive' about her new role in the royal family.
The former actress most recently wore a green printed dress by British brand Self Portrait when attending an Invictus Games reception on Saturday.
