Short pear - where to buy waist length t-shirts

[squidgesquodge]

I've spent the last hour forlornly traipsing the high street looking for some new tops and every one of them comes down to my thighs. This is a terrible length for me as it emphasises the width of my thighs and, to be big enough to circumnavigate my hips, thighs & bum, is then too big on my top. As the style is for them to be worn long, petite ranges make little difference.
Any advice? I last bought four perfect length tops in white stuff about 7 years ago but they're looking pretty old now - not a surprise given how many times they've been worn.

An evening bump

I got some in uniqlo last year- plain but good material.

Shops aimed at the youth market have them - Stradiavarius, Pull&Bear, Bershka...

H&M, they are made of cotton and are surprisingly good quality. I've had them for over a year and they wash quite well.
