Looking for a Red Blazer

I have seen a bunch of awesome style posts lately centered around a red blazer. It isn't an item that I really spent alot of time thinking about but it comes off as classic as a navy blazer and just as preppy.

Shop the Red Blazer (clockwise from the top):

1. Rag & Bone Bailey cotton and linen-blend blazer

2. Valentino Wool and silk-blend blazer

3. Spring Fashion Notched Lapel Three Pocket Blazer

4. Decorative Notched Collar Wool-blend Blazer

5. Jonathan Saunders Michaela two-tone stretch-wool blazer

6. Mango Double-breasted blazer

7. Wallis Red Blazer

So the questions are do you play up the preppiness and stick with classic colours? Or pair it with more casual fare?

And would you do a tomato red or a blue red.

Decisions, decisions.
