• Hacker News1Sizing chaosThe article explores how women's clothing sizing is fundamentally broken, with sizes varying wildly between brands and vanity sizing making labels meaningless. The current system is based on 1940s measurements of mostly young white women and optimized for mass production rather than actual body diversity. Most clothing is designed around a size 8 template, yet fewer than 10% of women actually fit those proportions. The author learned to sew her own clothes after realizing the industry prioritizes exclusivity over fit, and argues that since sizes are arbitrary anyway, the system could be redesigned to actually serve women's bodies.DIY clothing alterations:Discussion of sewing machines, tailoring, and laser cutting for custom clothing fits. Users share experiences with learning alterations, from basic sewing to advanced techniques like using DXF files for laser-cut patterns.Why sizing problems persist:Analysis of market forces behind inconsistent sizing, including vanity sizing for marketing, exclusivity strategies, and why retailers don't standardize measurements despite consumer frustration.Clothing industry targeting hourglass shapes:Revelation that most women's clothing is designed exclusively for hourglass body types despite this being a minority shape, leaving rectangular and other body types poorly served by mass market fashion.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
