Compare grey and burgundy together
A burgundy top adds warmth between a grey blazer and high-waisted grey trousers. It does not need to occupy a large area: the narrow centre of an open jacket can be enough. Cool grey looks different beside a blue-toned burgundy than it does beside a warmer wine red. Compare the pieces you own in daylight rather than relying on colour names when shopping. If the combination feels too dark, a small pale bag may be sufficient. Another bright shade is not required to make the outfit interesting.
Give the relaxed cut a quiet hemline
The top can remain relaxed beneath an oversized blazer, but it should not bunch heavily at the high waistband. Try a small front tuck and then a fully tucked version. Choose the one requiring less rearranging when you sit down. Generous blazer sleeves should still leave your hands free for writing. A neat cuff may help if the lining works for it. When the sleeve is simply too long, an appropriate alteration is often more useful than repeatedly pushing loose fabric back up your arms.
Repeat the idea with pieces you own
For the first attempt, wear simple dark shoes and a bag without a large pattern. That makes it easier to judge whether you enjoy the grey-and-red relationship. Later, repeat burgundy only in a scarf or bag and replace the top with cream. The grey trousers can also work separately with the red top. Think about which layer you are likely to remove during the day. The combination should feel complete with and without the blazer, so you do not keep an uncomfortably warm jacket on just for its appearance.
