Where to begin...
Let's start with underwear. I appreciate that some women want padded cups to their bras, but some of us, even though we are a humble B cup (ie me) do not want foam padding in our underwear. Can we have a choice please, at least? The choice of unpadded bras was far better ten years ago, and you could even get unpadded, un-cantilevered, non-rib crushing cotton bras from Calvin Klein. Can we have them back please?
I too share the armhole problem. Side-boob is not a good look an anyone, and unless your arms are huge, it WILL happen in a lot of today's sleeveless tops.
Talking of boobs once more, can we have fabulous evening wear that is not strapless, and has something other than an uncomfortable, cliched corset up top?
Right then, trousers. Most of us are not 5'9", and many of us do not have easy access to seamstresses, or the time or inclination to seek them out. Please stop making trousers excessively long, or at least give us a choice of lengths like men get. We don't all wear huge heels either, so that is not a get-out.
Oh dear, shoes. To sum up, all I want is shoes that stay on. Actually, I want flat, or low, square-heeled shoes that stay on. 90% of flats do not come far enough up the foot to stay on without toe-clenching, which hurts. I don't give a shit about toe cleavage apparently being sexy, I want my shoes not to fall off when I walk, godammit. Either put a strap across the instep (preferable), or make the uppers bigger. Oh, and please make the soles waterproof, at least.
