alt Hacker NewsAs a short adult male (5'5" - 165cm), it's always been difficult to find pants or jeans with a 28" inseam. Surprisingly, AmazonBasics line of clothes is one of the few mass produced consumer brands that has this size. Niche alternatives like Peter Manning are expensive, so it's great Amazon does this.
In theory, the claim in pants from retailers over time was that you could "just get them hemmed" — but if your jeans shape is bootcut or flare, then the leg curves sewn into the fabric will be in the wrong places for your knees, and/or you'll end up hemming off the flare. This gets especially frustrating in women's fashion because bell bottoms are popular, and there's no way to hem them without losing the 'bell' at the 'bottom' of the leg — but retailers only produce them in specific waist-inseam pairings, and so if you want to wear nice jeans with a nice flare, you have to get very lucky in finding them (especially if you're low-rise!) if they happen to exist at all.
