When Macy’s and Nordstrom’s dress selection just isn’t cutting it, many seniors and juniors turn to the online selection for prom dresses, which tends to have more shapes, colors, and sizes. Though most teenagers are pros at online shopping, sometimes making sure the website is legit is pushed to the back of our minds, in favor of gushing over the perfect dress you found on it. So you don’t get a 90% polyester 10% plastic dress three sizes too small right before prom, here are some websites and companies to avoid at all costs.

1. Wish/AliExpress

If it’s too cheap to be true it probably is. We all love to get a good deal on typically expensive dresses, but if a ballgown is 20 bucks that dress is going to have the fabric of a Halloween costume — if it comes at all.

2. Milly Bridal

Unfortunately, I personally had been sucked into the glamour of this “UK Based” website. It’s a popular site to order from, and sometimes they hit the mark, but it’s a gamble to order from this site. Though it claims to be a UK company, it’s actually Chinese, and it hits many of the markings of a scam website, including no refunds or returns.

3. Amazon

Amazon is great if you need a speaker or a laptop charger, not for couture. Sometimes there are great cheap finds, but if you’re thinking of ordering, do excessive research on the seller and see where they’re based and if they’re trustworthy.

These are the things to look out for on any dress website to help you see if it’s a scam:

1. You can order the dress in dozens of different colors
2. Shipping takes less than a month
3. The dress is “Custom tailored to your size”
4. No refunds or returns
5. A reverse image search of the dress appears on dozens of websites or the picture is ripped from an expensive fashion line
6. Website reviews are all five stars or one star — this means the company sends in employees to leave falsified positive reviews

Hopefully, these tips will help you not show up in a plastic see-through dress to what is supposed to be the best night of your senior and junior year. For further research, here is a master list of scam sites to help you along.
