Tight situation

For some people it's jeans, for others it's their pants. For me, it's tights. The main issue is that they either never fit, or they rip extremely easily. Why say opaque if they clearly aren't opaque once stretched over legs?! Why not allow me to return if I'm not happy with them? Why say ONE SIZE when clearly, everyone cannot possibly fit into the same par of tights comfortably? IT DRIVES ME MENTAL. Sorry, it's just that recently I've learnt the hard way to just draw a deep breath, delve in to my pocket, and splash out on a good few pairs of tights. Boots, Primark, M&S are a no go. Topshop and H&M yes please, a bit more pricey but all in all better to be happy, comfortable and poor than rich with bloody awful tights hey?! Rant over.
