The joy of following your own little drumming beat of fashion is that clothes can last you years! They don't look dated as it was never 'trendy' anyhow.
I've had this tropical dress from Collectif (use REE10 to get a sneaky discount) for years now, and despite a slight change in my style, I still find it a great go-to dress. Easy to wear (no ironing), easy to wash (chuck it in at 40 degrees), and always brightens a grey day.
Most trend advice seems to advise to buy a timeless black dress, but you can see I'm never short for inspiration as to how to wear this bright one.
