The term 'swag gap' has been trending on TikTok, with users warning that dating or befriending someone less 'cool' can lead to jealousy and resentment. The concept, popularised by model Julia Fox, suggests that a disparity in confidence, style, or career success can doom a relationship as the less swaggy partner becomes envious or tries to imitate the other.
Examples cited include Justin Bieber, who was accused of having a swag gap with his wife Hailey Bieber after she attended a New York event in a chic red dress while he wore a grey hoodie. Hailey's beauty brand Rhode recently secured a $1bn (£743m) deal, while Justin was on a career hiatus before releasing new music.
Critics argue the term sounds self-absorbed, but underlying it is a real issue: inferiority complexes can cause partners to lash out. Research shows men often feel worse when their female partners succeed, and pop culture examples like Ross Geller and Rachel Green in Friends illustrate the dynamic.
Real-life stories back this up. Aaliyah, 26, saw her journalism career take off while her boyfriend struggled. 'He was very insecure about what I was doing... he started to resent me,' she says. Issy, 25, a lawyer, ended an eight-and-a-half-year relationship with a partner who hadn't advanced himself. 'You cannot have a relationship with someone in a different league to you,' she says.
Couples therapist Joanna Harrison notes that differences in strengths are common, but problems arise when one partner struggles with something the other finds easy. 'This can lead to conflict,' she says, advising couples to address these disparities openly rather than letting envy fester.
