"This here jacket represents a symbol of my individuality and my belief in personal freedom" - Homer Simpson
I can never emphasize enough about the importance of a blazer / jacket for ladies. Even if it is to be a short-sleeved blazer, bringing some brightness and formal touch to the little black dress. Suitable for work and meetings - simply take off jacket for a night out afterwards.
Blazer: bought in Bangkok (around SGD$23.00)
Black cross-straps dress: bought in Hong Kong (around SGD$59.00)
