History has a crazy way of repeating itself, and so do fashion trends, but that does not mean all trends should make a comeback.

Recent trends have consisted of throwback looks from the '70s and '90s-- and let me tell you, some of them should have DEFINITELY stayed in their decade.

I'm going to apologize in advance to all of you who have fallen victim to these trends. I know fashion is a way of expressing yourself, but really-- jelly sandals when you are 20 years old? Slightly ridiculous looking. Here is the Hot and Not List of 2015:

1. SKIRTS

Plaid Skirts: HOT.

Denim Skirts: NOT.

Plaid skirts are a staple in almost every fall season, so it's a given that they are hot for 2015. This time, plaid skorts (skirt + shorts) are very trendy and also hot commodity.

WHY are denim skirts making a comeback? Don't get me wrong I absolutely loved my Abercrombie and Hollister denim skirts...when I was in 7th grade, but that ship sailed a long time ago.

Denim skirts are slowly re-appearing all over major department stores as well as smaller shops. As much as you may want to give in and purchase one to re-live your middle school days, absolutely do not. Don't do it.

2. SHOES

Platform Sandals: HOT.

For all you shorties out there like me, platform sandals are a lifesaver when it comes to your everyday outfits. You are not going to wear wedges everywhere you go when you want that extra height. Steve Madden, Dolce Vita, and Kate Spade have the best platform sandals for 2015, so I would advise you to go pick up a pair of these cute and practical shoes.

Teva Sandals: NOT

Just no. Unless you are going hiking or kayaking or better yet-- five-years-old and don't know how to tie your shoes, do not even think about buying these sandals. These shoes are the farthest thing from hot.

Birkenstock Sandals: HOT.

I know I just bashed Tevas, but those of you who are looking for a more natural, earthy-like sandal, resort to a pair of Birks. Recently these sandals have made a huge comeback after Birkenstock launched a new line of sandals with a ton of cool straps and new styles (the Yara sandal is my favorite).

If you still fit into your old Birks from 7th grade, bring them out of the box and start wearing them. For the rest of you who probably got rid of yours, go out and consider buying another pair, because you won't regret it.

3. NECKLACES

Beaded Choker: HOT.

$5 Plastic Choker: NOT.

Chokers have made a remarkable comeback this past spring and I'm not sure if I love it or absolutely hate it. Luckily, the choker necklace has been modified for 2015. Sorry girls- but ditch your $5 black expandable choker necklace and upgrade to something more mature looking with beads as opposed to cheap plastic. For those of you who are ready to re-vamp your choker and splurge a little, check out Free People or Urban Outfitters for some cute necklaces.

4. UNDERGARMENTS

Calvin Klein Underwear: HOT.

Day of the Week Underwear: NOT.

Normally I wouldn't have thought to put underwear on a hot and not list, but for this year it's almost impossible to ignore. If you didn't know before, now you know that "Calvins" are a super hot trend for 2015, but this isn't the first time they were all the rage.

Back in '92, Kate Moss began her modeling career campaigning Calvin Klein underwear with Marky Mark. Now these basic and practical- yet super trendy underwear are all over Instagram with the hashtag "MyCalvins" to promote the campaign.

7. HAIR

The High Half Up/ Half Down: HOT.

For those of you who have absolutely no clue what I'm talking about, you might be more familiar with the term "srat pony." When and why did a high half up/ half down ponytail coin this nickname? No idea, but it's becoming a thing.

Do you remember when you were a baby and your mother tied your hair in a ponytail so high on the top of your head with a scrunchie? Well, you can re-live your baby days because this hair style is back, and if you execute this pony correctly- it could be very stylish.

8. ACCESSORIES

Leather/Beaded/Printed Fanny Pack- HOT.

' 80s "Vintage" JanSport Fanny Pack- NOT.

For all you music festival goers, make sure you ditch your bulky crossbody this summer and try a practical fanny pack. I know it sounds strange switching out an adorable fringe bag for something your grandma used to wear all the time, but fanny packs are in now and back better than ever. Celebrities such as Kylie Jenner and Rihanna have been spotted sporting these functional accessories, so if they are wearing them, why can't you?

Disclaimer: When I say fanny packs are in, I mean ones with studs and print, not your mom's JanSport from the '80s. This stylish fanny pack below is by Show Me Your Mumu.

9.TECHNOLOGY

Disposable Cameras: HOT.

Digital Cameras: NOT.

It's time to put your small Nikon or Cannon digital camera away for a while, because photography has become old school again. Polaroid cameras as well as disposables are back, and I couldn't be more excited.

Although film is nearly impossible to get developed anymore and costs a fortune, it is still fun to use these devices at a festival, traveling, or shooting around in your spare time.

10. PANTS

Flared Jeans/Pants: HOT.

Capris: NOT.

Flared jeans have been in and out of style for a while now, but for 2015, they are most definitely in. The two hottest trends for 2015 in terms of pants have been flared and ripped boyfriend jeans.

Sorry capris, but your time here is up. Not only do flared jeans make your legs look slimmer, they are also perfect to pair with wedges. When wearing boyfriend jeans, style them with the shoes previously mentioned in #2 for a casual day look or pair them with a heel and you are set.
