Never heard of a "fat tax?" Let us school you.

A "fat tax" is what some countries and institutions place on certain unhealthy food items — think butter, cheese, pizza, and basically anything delicious — in order to dissuade people from buying those items and opt for healthier, cheaper alternatives. The Indian state of Kerala imposed the tax on doughnuts and other unhealthy foods, while Japan literally forces you to pay a tax if your waistline measures over what they consider "healthy." Say what?

The tax doesn't just apply to food.

UK body-positive Twitter account "Free to be OK with me" posted two screenshots of the same dress on Boohoo, one labeled "plus-size" and the other a straight-size. In it, the plus-size dress was labeled to be £5 more expensive than the straight-size. Not cool, Boohoo.

While we can't confirm the dress is the exact same style (the plus-size style doesn't have any product information listed on the site), it's still a miss for the online fashion retailer. 

Unfortunately, Boohoo isn't the first (and is probably not the last) retailer to spike prices on plus-size clothing. Old Navy has been in hot water for charging more for plus-size women's clothing, and we all know that bras are more expensive if you get a larger cup size. What gives?

Turns out, there's a logical reason for charging more for different sizes. A size 22 dress requires more materials than a size 2 dress, for example. Extra sizes also cost retailers more by way of manufacturing, as they have to source more fabric and build the style to be sturdier. Additionally, it's the law of supply and demand — enough customers need to be requesting plus-sizes in order to balance out the cost it takes to produce them.

That still doesn't make it OK for Boohoo to charge more for the same style, though. For a site that's constantly offering sales and discounts, it doesn't seem like a leap to offer garments at a slightly higher cost to balance out whatever additional costs might be associated with making a plus-size article of clothing. Just a thought, Boohoo!

Additionally, the retailer has been in hot water before, primarily over the models it chooses to cast. Most of the models wear a UK size 16, which is roughly a US size 12. However, UK plus-sizes start at size 18, which means the models showcasing plus-size clothing on the site aren't even plus-size. 

Do better, Boohoo.
