Love Island star Cassidy McGill was slammed for wearing a bra that showed off her cleavage while wandering religious tourist spots in Milan: “Aren’t you arrested yet?”

An Australian influencer has been criticized for wearing a revealing bra without a top while visiting Milan, Italy.

Love Island star Cassidy McGill is currently enjoying a lavish vacation in Europe and on Tuesday she posted a carousel of photos to Instagram from her trip to the fashion capital.

While sight-seeing, she flaunted her ample cleavage in a black bra paired with a low-waisted white maxi skirt.

In one photo, she was seen dancing in the revealing outfit outside Milan’s historic cathedral.

Another had her pose in a popular indoor mall.

The influencer captioned the snaps: ‘Milan for 40 hours in my glorified bra!!!’

One angry person mistakenly thought Cassidy entered the cathedral in the outfit and wrote, “Wait. She entered a church wearing only a bra and skirt?’

It later emerged that she was wearing the outfit at the famous Galleria Vittorio Emanuele II shopping mall.

While another said: ‘Apparently a bra can pass as top in Italy’

And a third wrote: ‘And you haven’t been arrested yet xx’.

However, many of Cassidy’s fans said they liked her outfit.

One fan wrote, “Men can walk around shirtless, I see no problem with your top! :)’

And another said, ‘Bra or not, you still look gorgeous. Milan looks fantastic! The mozzarella stick looks delicious’.

Cassidy has been contacted by Daily Mail Australia for comment.

It’s because those traveling to Europe have been warned they could be fined for their outfit choices.

In Italy, bikinis are strictly for the beach and wearing them in town can result in fines of up to $800.

Last year, the southern Italian resort town of Sorrento was fined more than $800 for those who wore inappropriate swimsuits when not in the sand.

Other cities, mainly in the south, have similar local sanctions to Spanish cities such as Barcelona and Mallorca.
