The McQueen exhibit at the Met is leaving August 7. If you haven't already gone, you simply must. Simply. Must. You can't take photos in the gallery, but I'll give you a peek from the exhibit book.
This exhibit is crazy busy. If you can, buy a ticket for a Monday. The Met is closed on Mondays, but they are opening especially for those who have bought tickets for the McQueen exhibit. If you can't go on a Monday, make sure to get there right at 9:30 when the museum opens. Trust me. It'll be crowded even then.
Before your museum trip, you might want to have an 8:00 breakfast at Pick-A-Bagel, only a few blocks from the Met.
After wandering through the exhibit and the other gorgeous offerings at the museum, you can get a tasty from the nearby food trucks and head to Central Park to watch the kids racing motorized sailboats and whatnot.
If you've still got the energy, hop on a train and go to the Pink Pony on the Lower East Side. Oh, the place is so, so wonderful. From there, it's a short walk to the shopping district of Soho. That's where, if you're a knitter or quilter, you can find the legendary Purl Soho.
As for dinner, you can find plenty that's wonderful and awesome in Soho, or you can head to the High Line in Chelsea and eat some gourmet food from the fancy food trucks. After that, hop in a cab and ask to go to the 675 Bar. Once there, order a drink with the Earl Grey-infused vodka.
After all this, wander back to wherever you're staying and sleep a satisfied sleep.
In the morning, head out to the local markets and buy the kind friend who let you crash on her couch some flowers. Or, hell, buy yourself some flowers. If nothing else, you can put them in your hair. Or, if none of that sounds suitable, just enjoy looking at the flowers. There's satisfaction in that, too.
