People have deduced that there is a trend cycle of about 20 years. That's how long it takes for something to come back into style. Things millennials grew up with are now considered vintage and back in style.

They spark nostalgia, and people can't seem to buy them fast enough. Companies often use nostalgia to sell merchandise, as it tends to always sell well.

With the trend in vintage products growing, here we're looking at six of the best subscription boxes that can help you feed your nostalgic cravings.

1. Unique Vintage Dress of the Month Club

If you love vintage-style clothing, you should check out Unique Vintage. It offers a Dress of the Month Club box for $50. As the name lets on, it grants you a dress that matches your preferences each month.

You give your size, pick a subscription, and enjoy the garments you get. If you don't like what Unique Vintage sends you, you'll get refunded for that month, and if the dress doesn't fit, you'll get sent another one that's the correct size.

The Unique Vintage website offers a look into the past dresses it sent out, so you can check them out and see if they match your vibe. If you like how they look, give Unique Vintage Dress of the Month Club a try.

2. Vinyl Record Club

There's nothing like listening to music on vinyl. If you're a music lover who appreciates that, San Diego Vintage Collectables offers a Vinyl Record Club you can join for as little as $26.99 per month.

You select the music type and genre you like and choose your subscription, and you can receive six vinyls a month. You're free to switch genres at any point, so you can diversify your collection. Some of the records may look a bit worse for wear, but there's a guarantee that they're all playable and won't skip.

The Vinyl Record Club keeps expanding its collection, so you're sure to find something you like in its stock.

3. A Curated Thrift

A Curated Thrift offers several subscription boxes that get you second-hand clothing pieces curated for your style and size. All, without you having to rummage through thrift shops for hours.

There are three subscriptions available: My Vintage Box, My Thrift Box, and My Deluxe Box. They cost $34.95, $49.95, and $69.95, and get you one item, two items, and four items, respectively. The four pieces from My Deluxe Box get selected to go together as a cohesive outfit.

When you sign up for a subscription, you take a style quiz and select the aesthetic that most appeals to you. Anything you don't like, you can send back, and if you need to exchange a piece, it's free.

Thrifting is great, but it can be exhausting to browse different shops looking for the right style and fit. A Curated Thrift takes on that responsibility for you, so why not give it a shot?

4. Retro Candy Club

Who doesn't remember that specific piece of candy that was quintessential to their childhood? It could have been a candy bar, ice cream, a powder, a liquid, but it was the one thing you looked forward to getting every time you were at the store with your mom.

The Retro Candy Club knows the power childhood candy holds over people, so it offers several monthly subscriptions that cater to different decades and the treats most popular in them. There are five boxes to choose from the 1950s, 1960s, 1970s, 1980s, and 1990s.

For $25 per month, you get over sixty retro products that hold a $50 value. The box gets packed with candy and snacks, along with secret surprises and gifts from the decade you chose. What you get may be retro, but it's fresh and delicious.

5. Retro Game Treasure's Treasure Chest

If you're a game enthusiast, check out Retro Game Treasure. It offers a Treasure Chest box that contains three to five retro games.

If you choose to subscribe, you have to select which styles you're keen to play. There are over ten categories to choose from, which helps Retro Game Treasure learn your gaming preferences.

It also only sends you games for the console/s you have, so you won't get stuck with games you can't actually play. You won't get duplicates, either, and there is also a List of Shame that contains games so bad no one wants to play ever, so you won't get sent these, too.

If you've already started a retro games collection, Retro Game Treasure is more than happy to help you fill in the gaps after you share the titles you already own. It offers a subscription for one, three, six, or twelve months, and it costs $35.99, $101.97, $191.94, and $359.88, respectively.

6. Comma Vintage

Comma Vintage caters to the men who like vintage clothing. It offers a Season by Season subscription that charges $59.99 every three months and a Full Year (Four Shipments) one that costs $219.99 and gets charged every 12 months.

It sends you American-made pieces from famous brands that fall under various styles. Comma Vintage curates items that match your preferences, and it manages that because it makes you take a quiz. After choosing a subscription, you get a style survey and, among other things, get asked to give your size and body type.

You can get vintage menswear, accessories, and even artifacts from the past with a Comma Vintage box. You can check out some of its previously sent boxes in the Blog section of its website.

Give Into Nostalgia and Reminisce Away

If thinking back to your careless childhood days, while munching on a candy bar from that era helps you get through the day, go for it. Nostalgia can be a mere marketing ploy to sell you products you don't need, but it can also be a great thing that brings you fond memories of a time passed.

Give in to your nostalgic feelings and find the subscription that will help you feed the kid in you, whether it's with candy, games, or clothes.
