The Ultimate Backstreet Boys Concert Checklist, From Butterfly Clips to an All-White Outfit

Hosaily Roll-on Holographic Body Glitter ($8)

Remember dousing yourself in body glitter before a big dance, sporting event, or even just a regular school day? Body glitter, especially roll-on, was a very big part of my childhood, and it makes the perfect finishing touch for a Backstreet Boys show. Fans were glistening in the crowd, and I was actually so jealous I didn't have any. If I were to go back, I'd 100 percent purchase this.

Jasverlin Glitter Mini Butterfly Hair Claw Clips ($8)

Nothing says early aughts like butterfly clips, and they were everywhere at the Backstreet Boys show. I popped a few into the front of my hair for a little throwback moment, but fans really went all out with space buns and braided looks — total Y2K energy. The best part? You don't have to hunt them down at Claire's anymore, just grab a pack on Amazon and relive your teen-dream era with two-day shipping.

Pistha 12-Pack Bandanas ($9)

Wondering where the heck your touch of blue is going to be? Consider a bandana like this one. The light blue color is very millennium, and it can be worn in your hair, as a top, or even tied to your belt loop. Plus, a 12-pack means there's more to go around — trust me, you won't regret having extras.

Hanes Ecosmart Cotton Tank ($13)

I was heavily influenced by Kendall Jenner's viral Hanes tank and can attest to its versatility. I've worn it lounging around the house, out to dinner, and now to a Backstreet Boys concert. I seriously love it, and it's especially great for layering when you want that early-aughts vibe. Keep in mind that this is a boys' tank, so I went with an XL for the size. It fit a little big (a large would've been perfect), but it still worked out just fine for my 'fit. Read my Hanes Ecosmart Cotton Tank review.

Editor Quote: "Aside from the unbeatable price, there's honestly a lot to love about this ribbed white tank. For starters, the cut does something my usual tanks just don't. That swooped neckline? It somehow makes the whole thing look effortlessly chic. Plus, it goes with anything. Sweatpants? Definitely. Denim shorts? Obviously. A skirt and some jewelry? Absolutely. Case in point: Jenner styled hers with leather pants, and it looks totally high fashion." — Haley Lyndes, assistant shopping editor

knliwkm Rimless Rectangle Sunglasses ($15)

Yup, everyone was rocking these rectangular sunglasses — the same style the Backstreet Boys themselves have worn. I personally loved the pair with the butterfly detail (very Y2K), and the light blue lenses instead of dark ones are a nice touch, so you can actually see. Trust me, you'll want to take in every visual The Sphere has to offer.

BodyJ4You 12PC Tattoo Choker Necklace ($20)

Choker necklaces were everywhere — including on me. I went with a white one, but plenty of fans used theirs as their touch of blue. However you choose to wear it — on your neck, wrist, or even leg — chokers were giving total early-2000s nostalgia. Honestly, I felt like I was getting ready for a middle school dance all over again.

Y&R Direct Clear Bag Purse ($24)

The Sphere has a strict bag policy. It's called a "no bag policy," though that's not entirely accurate — you can bring a bag inside. The rule mainly restricts large bags and backpacks. Only small clutches, purses, or fanny packs, roughly 6 x 6 x 2 inches, are allowed. That "roughly" is key: as long as your bag is close to that size, you'll likely be fine — they're definitely not measuring down to the millimeter. That said, finding a bag that small is surprisingly tricky. For example, this crossbody measures 8.3 x 4.9 x 3.3 inches. Its length is just slightly over the limit, but it would still be allowed.

Bodyogrophy Glitter Pigment ($24)

Who says your touch of blue has to be worn? Let it glow instead. This glitter pigment doubles as eyeshadow or a soft wash of blue shimmer on your shoulders and chest, adding just the right amount of sparkle. It's the easiest way to level up your outfit — no extra layers required.

Carbon38 Strappy Tank in Melt ($108)

This tank top has to be one of my favorite purchases ever. I wear it all the time — the material is buttery soft, and the cut is so flattering. The fact that I've owned it for two years without a single stain on its gorgeous white fabric is kind of crazy, but that just shows how much I value it. It made the perfect layering piece under my Hanes tank for the concert, and the built-in bra is such a nice touch. That said, you'll get plenty of wear out of this top on its own, too.
