Stylish Party Dresses Under $50? Challenge Accepted

#StayClassy during the festive season with these cute dresses

Find a dress that's:
1. Appropriately festive (read: something that's red, green or has glitter and shine)
2. Sexy, without being too OTT.
3. Cheeky enough to be a fun party dress, but practical so you'll wear it over and over again.
4. Not black, because we've got a couple of LBDs already.
5. Under S$50
