I have to disagree with you about the pant legs, if there are no options for different lengths, it’s much better to have them too long. I’m 167cm and even I have a problem of finding long enough jeans, the L30 is always on stock and 32 and 34 are always sold out or not available. It’s so much easier to hem than to add more 😅 We have jean stores here that hem the pants for free for you.
I completely glossed over the tape measure thing so I had to pull out some to check if mine are accurate. It doesn’t look like it in the picture but they are all very very close to each other, the clothing tape measure is the odd one out but that is actually pretty normal, they can stretch over time, especially cheap ones because they are soft plastic.
I’m not having a go at pant lengths being too long. I get my wife to hem them but if you don’t have that ability then here you have to pay to get them hemmed. It might be different if say I bought a suit as generally they will do it as part of the fitting.
But if I buy a pair of $20 jeans at The Warehouse it’ll cost me about $20 to get them hemmed otherwise because The Warehouse doesn’t have a fitting service. It’s not worth it.
I never thought about the stretching thing. Both tapes I have/had are fibreglass so not supposed to stretch but they will break, hence my problem.
It is interesting to me though that the tape I just bought is more inline with reality though. I’m now measuring at 87cm which is what my pants are. The one that broke was telling me I was 77cm which is better for my ego I guess but not inline with reality.
I just thought it was interesting that there could be such a discrepancy with something that should be a standard measurement.
