Buying clothes couldn't be easier thanks to online shopping. But there's always that risk that what you've ordered will look nothing like it did on the website.
Unfortunately, one woman got way more than she bargained for after she received her Shein order.
Nayelis Bido had ordered a "bunch of stuff" from the online fashion store, including a white bikini.
But when the two-piece finally arrived, she couldn't believe her eyes - it had an unmistakable stain in the crotch area, she claims.
She posted a video of the bottoms on her TikTok @nayelis.x, where it has since gone viral, amassing 493,000 views.
"if you buy from Shein you gotta watch this video," it was captioned.

"I literally got a bikini bottom with discharge, and I'm gonna show you right now," Bido said.
She held up the offending white bikini bottoms that she ordered which clearly featured a yellowish stain in the crotch area, that according to her, arrived like that.
"I already checked everything and the only problem here is this guy. And when I saw this little stain right here I was like you know what, maybe I can take that off with something, maybe it got dirty or whatever.
"And then when I opened it I was like woah, wait a minute. There's no way that's discharge. But yeah, it is.
"I'm a woman and I know how discharge looks, and that's definitely discharge. And it's disgusting the fact that they send it like that."
Nayelis said she was disappointed to have received her order this way since Shein is one of her favourite online stores.
"It's disappointing and it's unprofessional and I'm very upset.
"I really wanted to wear this bikini set but I won't be able to. Not even if I wash it off, I still don't wanna wear it."
She urged other fans of the store to wash the items before they wear them for this reason.
Since being posted, the video has racked up more than 57,000 likes and 1,500 comments.
One person said: "It doesn't have a sticker either so definitely used," to which Nayelis replied: "That's what my mum said!!"
Another wrote: "Don't encourage people to wash it off, send it back!"
"Why are you touching it?!" exclaimed a third.
Someone else put: "This is why I wash every clothing item after purchase. Even socks lol. Same for towels/blankets/etc."
The Mirror has reached out to Shein for comment.
