Fitness star with natural 30H breasts (and 3.5 million Instagram followers) details the downsides of being so busty, from fashion fails to awkward 'boob sweat'

• Instagram star Lindsey Pelas, 24, measures between a 32DDD and a 30H
• Though her breasts are real, she constantly fends of questions about whether they are fake and why she'd choose to go so big
• She happily shows them off on social media, but notes that there are bad things about being busty too
• Bra shopping is 'the worst', clothes don't fit, men stare at the gym, and long necklaces and cross-body bags get lost in her cleavage 

When it comes to breasts, bigger isn't always better — despite what some men (and women) might tell you.

Just take it from Instagram star and Playboy model Lindsey Pelas, 24, whose bra size is anywhere from a 32DDD to a 30H, depending on who is measuring her (totally real) breasts.

'You might think having big boobs is amazing, but there are actually a few disadvantages that I'm here to share with you,' she says at the beginning of the clip.

For one thing, she says: 'Every time a girl who's super-busy bends over, she has to hold the girls, or they're going to fall out.' She them demonstrates for the camera.

'Also, you always look vulgar in regular clothing. It can be a T-shirt, a floral dress, a wedding dress, a nightgown, whatever. When you're busty, you just kind of look like a porn star [by] accident.'

This is, in fact, and age-old complaint of the big-busted, who can manage to look indecent in a top that a smaller-chested friend might look chaste in. Yet Lindsey herself doesn't seem to totally mind the 'porn star' look at least sometimes, as she shares Instagram pictures of herself in racy corsets, see-through tops, and — sometimes — no top at all.
