The only way that I can get swimsuits to fit properly without cutting into me is to buy two pieces. I now buy tankini pieces from Lands end - regular high-rise bottoms, but long size top and they're just right.
So far as trousers are concerned, I can take up hems but the proportions still don't seem to be quite right. I find that certain makes of sports leggings are a bit more forgiving but - of course - they don't work for formal wear.
I do look for high-rise trousers.
I recall finding a particular cut of Levi's jeans that worked for me in the late '70s, but - alas - haven't found anything in formal wear that's quite so good.
My current jeans had to be bought a bit bigger than I would have liked. I took up the hem and I wear them with a belt, but they're still not right.
I also find that I can have a problem with certain dresses and jackets - the waistline often sits too high up and just looks odd: I tend to look for the
type that just skims and doesn't have noticeable pockets. (I do like pockets, but if they have a flap, then they're noticeably in the wrong place.)
Jumpers and t-shirts intended for men tend to be a bit better for length, but then the sleeves are often too wide or too long. Yes, I do roll up sleeves where that's possible or adjust as best as I can.
Honestly someone feeling the need to tell us to alter clothes where possible is a bit insulting...As if we'd never thought of that!
And yes - I am overweight, but I had the same problem with clothes when I was the same height that I am now - nearly 5ft 9 - and 8 stone 10 lbs. Even when I was a child, I recall my mum having difficulty getting clothes to fit because I had a long back. She was good at altering things, so she'd buy bigger and take in where necessary.
Once I was 11 yrs old, however, she had problems finding clothes suitable for my age group.
I feel sorry for the girls who have been told (according to various news reports) that their brand new uniform skirts are too short. I recall having great difficulty finding midi length skirts in my size.
As a teenager, I was in a band. There were only four girls in the group - there were 5 boys - and we all went to the same shop to purchase matching black skirts. The other three girls all got identical skirts that went below the knee. Mine was just above the knee. I certainly wasn't fat - I was the same height that I am now and had a 26 inch waist.
