A KEEN gym-goer has been left mortified after realising her PUMA leggings were completely see-through.

Kimberley Williams unleashed a scathing review of the transparent gym clothes, saying the company needed to introduce "booty tests" on their items before they hit stores.

The 27-year-old nanny said: "Well firstly I was pretty annoyed that I brought a new pair of gym tights that were completely see through.

"I have not worn them since they are pretty much just sitting in my draw. I am unable to return them also as they were a sale item.

"You would only expect this in cheap made leggings but wouldn't have expected it from PUMA considering they are a sportswear company. Who would honestly want to buy them knowing you can see everything. No normal person would.”

The former personal trainer said she only realised why she was getting funny looks from people when a friend pointed it out.

Kimberley, from London, wrote a post to PUMA’s official Facebook page about the incident and even posted a photo as evidence to ask if they conducted “booty tests” on their products but the company never responded.

Describing the traumatic event, she said: "It was a cold London morning and I had taken myself shopping to buy some new gym leggings. As I sorted through the racks of leggings upon leggings the simple yet stylish black puma leggings caught my eye.

"I decided to do it and purchased myself a nice pair of puma gym tights!!

"Saturday morning I sprung out of bed in utter excitement to show off these new black puma leggings."

She added: "As I waltzed down to my gym with not a care in the world I could feel all eyes on me. People were clearing checking out the new leggings I had purchased and I digged it.

"Ready for my tabata class I was feeling super energized and super stylish in my new puma leggings. As I bent down to stretch out my legs my friend gasped in utter shock... ‘Kim I can see your a**e’."

The nanny said she checked her leggings in the mirror - saying she was disgusted.

She wrote: "Much to my disgust as I bent over in my new gym tights my whole a**e was showing, through my simple yet stylish puma gym leggings. ‘How could this happen to me’ I thought to myself. Were puma out to humiliate me!!

"I ask you puma do you booty test your items before they hit the stores? How do I know if I can trust your products again from not giving my whole gym a view of my ever so peachy a**e??"

The woman said she tried to laugh off the situation but said she was still annoyed at PUMA - and their lack of response.

She said: "Luckily I have a sense of humour so I laughed it off and made my friend go behind me in our gym class so at least she had a view of my bum as opposed to the whole gym class

"I think PUMA should possibly look into how they quality test their materials before putting the products out to be sold."

A PUMA spokesperson said: "PUMA offers leggings of different materials in its product ranges, catering to a wide variety of consumer preferences.

"In case, a customer is unhappy or dissatisfied with the quality of a PUMA product purchased, we have a return policy in place that guarantees that the product will be replaced or refunded."
