That is absolutely not true, you might just be out of touch. Baggy clothes are extremely popular right now, compared to 10-15 years ago when skinny jeans and hipster fashion were popular. Now alt fashion is becoming mainstream on TikTok, with baggy cargos and oversized T-shirts and bags with straps replacing beanies and glasses with big frames. Honestly I think saying fashion hasn't developed sounds very reactionary, it's in the same vein as people who say that there is no modern culture and all music is worse now
