BEST BUST: This is the ideal boob size, according to men

Womens’ breasts come in all kinds of different shapes – in fact there’s nine boob variations in the world – but what’s the perfect size?

To find out what men find most attractive, researchers at Prague's Charles University quizzed lads from four different countries about their chest preferences.

The 267 men, from Brazil, Cameroon, the Czech Republic and Namibia, were shown two sets of images of ladies’ assets including boobs of varying size and firmness.

It turned out that the majority of men favoured a medium-sized set, followed by large and then small breasts.

But when it came to firmness, it was clear that the men from all four countries favoured this trait.

This means that guys generally prefer shapely, perky boobs rather than large ones that might become saggy with age.

Scientists reckon that men are attracted to boobs because they rely on visual cues to evaluate a potential mate and mother of their child.

Ladies with bigger breasts have higher estrogen levels, indicating that they are more fertile.

While most people think a C-cup is the average size in the UK, a recent study revealed this is no longer true.

In fact, it seems there might be something in the water as the average British bust size is a whopping 34G.

But which region has the largest assets?

The biggest boobs can be found in Scotland, where the average lady has 34HH baps.

Breasts in Wales are also voluptuous, with the average lady measuring in at 34GG.

While the smallest boobs (which are still pretty sizable) are found in the south, where the most common bra size is 30G.

And the Midlands, Northern Ireland and the north, measure in at 32G, 34G and 36H respectively.
