It seems that Taylor Swift and her friends love a good dress up party now and then. But these girls aren’t donning black miniskirts and red high heels for a night on the town. No, they’re more likely to be found in ribbons and lace, looking more like something out of ‘Breakfast at Tiffany’s’ than ‘Sex and the City.’

Earlier this year, Swift tweeted a photo of herself and friend Claire Kislinger playing dress up in what seemed to be vintage wedding dresses ornamented with strands of pearls. Swift completed her fairytale ensemble with a veil and a pair of oversized sunglasses, while Winter tucked pink flowers into her hair.

The two girls were at it again this week, tugging at their inner little girls as they hit the town adorned in more vintage lace dresses. And this time they were accompanied by two friends — one of whom was Dianna Agron from ‘Glee’ — to celebrate the 77th birthday of actress Shirley MacLaine. “We dressed up full-time fancy and went out in celebration of Shirley MacLaine’s birthday,” Swift shared.

In a series of Instagram photos, Swift and her trio of girlfriends can be seen getting ready to go out, looking nymph-like in their pale hues of pinks and whites. With each girl sporting faux flowers or a dainty hat on her head, they headed out to celebrate. In one photo, the girls look quite pittoresque in their dresses, sitting together in what looks to be a restaurant. Another snapshot caught a plate with a dessert in the corner and “Happy Birthday Shirley MacLaine” scrawled out in chocolate sauce cursive.

All in all, it looks like Swift and her friends know how to creatively have a good time — and look quite classy in the process.
