Help for work clothes now it's getting warmer... bring me your lovely tunics

[SarfEasticated]

I always wear, leggings, knee length boots, long knitted tunic or sweater dress to work. The A/c is always up quite high so never very warm {bitter}.
I feel I will need to refresh my wardrobe for spring. I have just bought a lovely birdy scarf from John Lewis (teal, pink and green birds on white background (not on website yet) and a teal Zatchels saddle bag. I feel like I need some new plain tunics in a light knit, but can't find any online. None in Boden, this in Toast but rather dear at the moment. Not sure where else to look. I like clear colours rather than the muddy faded shades loved by Seasalt and White stuff.
Any suggestions oh great sartorial oracles?
