I started a new job 3 months ago. Work Christmas do is Friday. It’s a 3 course meal, free bar and dj night. Said I’d go but I don’t want to wear a dress and can’t find a jumpsuit I like and I’m quite short and I’m just feeling quite frumpy atm. So it’ll be nice tapered/dressy Zara trousers, sparkly long sleeve top, heeled boots, necklace and jewellery etc and I’ve had my nails done. Probably curl my hair and some makeup. But I heard my colleagues saying they’re wearing dresses and it’s made me not want to go now. Aibu?
