1. Back in the '00s, two-piece tracksuits were a ~thing~.
2. A pretty damn stylish ~thing~.
3. Basically, anyone who was anyone wore a two-piece tracksuit.
4. I mean, just look at Brad Pitt coordinating his tracksuit with his cap and sunglasses.
5. And look at Coleen Rooney pairing hers with a crochet beret and Uggs.
6. Back then, wearing a tracksuit that showed your midriff was considered chic.
Lisa "Left Eye" Lopez, J.Lo, and Miss Dynamite knew it.
7. Wearing three-quarter-length tracksuit bottoms was considered red carpet appropriate.
8. Tracksuit hoodies were appropriate for book launches.
9. And forgoing a top underneath your tracksuit hoodie was considered the height of glamour.
10. Wearing hoodies to fancy events was 100% OK back then.
11. Accepting awards in a tracksuit with a matching furry hat was perfectly legit.
12. And nothing was cooler than coordinating your tracksuit with the rest of your band.
13. Basically, however fancy the event, wearing a tracksuit was considered appropriate.
Here's Samantha Mumba and Mis-Teeq rocking theirs on red carpets, and Madonna leaving the literal Ivy in hers.
14. If you were in a girlband, at least one member had to be in a tracksuit at all times.
16. At all times.
17. Of course, the most iconic look of all was the baby blue Juicy Couture number.
Everyone wanted to be Britney and Paris in these photos.
18. But the pulled up G string was one of the great looks of its time too.
This is Geri Halliwell, also dressed for lunch at The Ivy.
19. But our love of velour didn't just extend to tracksuits. We made suit jackets out of it too.
20. And we made some beautiful dresses.
Imagine looking as good as Jamelia and Paris Hilton.
21. The '00s were a more relaxed time.
22. And we will forever remember the tracksuits of the past.
If only Mel C and Victoria Beckham would dress like this now.
