You won't get turned away. In this day and age, cross-dressing is (officially) fine.
However, I also agree that you'll look like an idiot as it's not what people do when they go the match. It's not a party or a stag do. If you were normally wearing dresses, that'd be fine, but doing it to spruce up your day just seems odd. I mean, people used to go in Sunday suit and tie in years past. These days, its all about dressing up but not looking dressed up, lol. And lots will say that only wools wear Liverpool shirts to the match.
