I've plumped for my white Zara light knit jumper with sheer shoulder panels that I bought about 2 years ago. There are still a lot of sheer panel styles around this season like the current Zara version I've chosen for my outfit builder. The colour and sheer fabric make it summery enough but gives coverage too.

Obviously I can wear jeans for my work but if you wanted a smarter look I'd opt for a patterned crop trouser, like these at H&M.
