Clothing that features slogans joking about stalking has been slammed by the Suzy Lamplugh Trust, a London-based charity which aims to 'make society a safer place'. A number of online retailers stock the offending garments, which feature phrases such as  'I heart my stalker' and 'Some people call it stalking. I call it love!' According to the SLT, the T-shirts mock a serious issue which affects one in six women, and play into people's fear of being laughed at, which prevents victims from seeking help to deal with stalkers and puts them at a higher risk of being attacked. Scroll down for video . Funny? A selection of T-shirts (pictured) branded with jokes about stalking has been slammed by The Suzy Lamplugh Trust, a charity which aims to 'make society a safer place' The T-shirts in question are sold in US and UK stores including Zazzle, Look Human and North Shore Shirts. 'Are you stalking me? 'Cause that would be super', reads one, priced at $10.99 (£7.40) in the US. 'I stalk you on Facebook', another states, priced at £16.95 ($25.35). 'Stalking is when Channing Tatum and I go for long romantic walk together but only one of us knows about it', another $28 (£18.90) specimen muses. 'Stalking is such a strong word, I prefer intense research of an individual,' reads a $27 (£18.11) shirt, featuring the  description: 'Sometimes when you want to bag a mate you have to do some reconnaissance.' A spokesman from the Suzy Lamplugh Trust told MailOnline that these common slogans seem harmless but they prevent the crime from being taken seriously. She said: 'It does all add to the feeling that it’s something that’s a little bit humorous. It’s not, especially for victims. Making light: According to the SLT, the T-shirts mock a serious issue which affects one in six women, and play into people's fear of being laughed at, which prevents victims from seeking help with stalkers . 'If we're  still making jokes about stalking it’s harder for victims to come forward. 'Things are sold with humour but when they’re so commonplace they start to dilute the language around them it starts to become a problem and stalking is a serious offense. 'It doesn’t help that the messages are out there, it just reinforces the myths that are around stalking.' She added: 'Even the language around stalking is potentially damaging, we all talk about stalking people on Facebook but we don’t mean it, we mean we’re looking up someone we went to school with. She said a common view of stalking is that it's romantic, with stalkers leaving bunches of flowers, teddy bears or money on victims' windscreens. 'The behaviours may not seem offensive in that way but if it’s unwanted attention from someone, it’s a problem.' Offending articles: The T-shirts in question are sold in US and UK stores including Zazzle, Look Human (pictured) and North Shore Shirts . In honour of National Stalking Awareness Week, which started on Monday, the personal safety charity, which runs the National Stalking Helpline, has released a two-minute animated film to help shift the public's, at times, blasé perspective on the matter. The video's voiceover states: 'What does stalking actually mean? 'It doesn't just mean a stranger ambushing you from the bushes or lurking through the window. 'It can also mean disturbing emails, non-stop phone calls, creepy letters and social media abuse. It means the other person ignores your "no". 'It means you're forced to change your life routine for months or even years. 'Oh, and it's not flattering or funny, it's a serious crime. 'So if you're being followed, if there are eyes on you wherever you go, if you are scared to open the door or your mailbox or your text messages, if you jump every time the phone rings, if you haven't had a good night's sleep for a very long time... then this is stalking.' According to the campaign - which seeks to challenge the notion that stalking is 'romantic, trivial or funny' - 80 per cent of victims are women, and more than 80 per cent of men and women combined are stalked by someone they know. Of this, 45 per cent of stalkers are ex-partners, 22 per cent are 'acquaintances', five per cent are colleagues or ex-colleagues, and four per cent are family members. 'It is hard to give an exact definition of stalking because stalkers will often use multiple and differing methods to harass their victims,' the trust explains. Serious crime: 'It is hard to give an exact definition of stalking because stalkers will often use multiple and differing methods to harass their victims,' the SLT explains (picture posed by model) 'Stalking can consist of any type of behaviour, such as regularly sending flowers or gifts, making unwanted or malicious communication (including calls, texts and emails), damaging property and physical or sexual assault. 'If the behaviour is persistent, unwanted and is causing you fear, harassment or anxiety then it is stalking and you should not have to live with it.' The SLT was set up by Diana Lamplugh, the late mother of Suzy, a 25-year-old estate agent who disappeared in Fulham, south west London, in 1986. She was presumed murdered and declared dead in 1993, and no one has ever been charged over her killing. 'Our mission is to campaign, educate and support people to help reduce the risk of violence and aggression for everyone,' the charity states.
