Everything already mentioned!!! The faux or vegan leather is a particular peeve of mine too.
And I'll add -
Why can't you just tell me the shoulder measurement?? Because if it fits in the shoulders, almost anything else can be altered. Maybe this is particular to me, but shoulder measurement tends to be the single biggest predictor that a garment may actually fit me.
Not telling me the rise measurement - only saying it's "mid-rise" or "low-rise" or "high-rise" - terms that have zero consistency anymore for most brands.
Enticing me with a thumbnail and title that seems to indicate a garment offered in a zillion colors is also available in petites, but then when I get to the petite page, it's only available in a single color, usually black. And you wonder why I wear so much black. That's all, apparently, petite people like to wear.
Petite sizing that is designed for people exactly 5'4" tall, but then saying on your sizing guide that petite sizing is designed for people 5'4" " and under".... there is a very very big difference between someone 5'4" and only 5'0... or shorter.
Petite sizing that is just right in the length & proportion, if only I'd lose about 20 lbs.....and despite gaining weight recently I'm still well within normal BMI. I am all for having a range of sizes for the skinny mini petites. It's just that when I size up, I'm now in 5'4" range and the proportions are all wrong.
No tall boots for those of us with narrow calfs AND short legs. I am getting desperate here. Even Duo boots assumes that all petite people can fit in a 14-15 inch shaft boot. I'd like to know who are these 5'0 tall people with 12 inch calves and 15 inch lower legs??? Because my golden ratio proportions are supposedly "ideal"-- and that is an over-the-knee boot on me!!! Okay, so I am willing to pay for alterations for the right boot - but the boot styles have all sorts of detailing on top which makes such alterations impossible. There may be a handful of boots out there that will fit my measurement, but they are all boring black and chocolate brown, or they are cowboy boots. I want COGNAC boots. Please. How many friggin' years have I been looking? Sigh...
Having to wait until a trend is past peek to be able to find it offered in petites.
Expensive handbags that hide their security tags so well, even the sales clerks can't find them. Then every time you enter any store, you set off the alarm bells...
Facebook feeding me ads about clothing I already just ordered. Kind of redundant, no? Show me something else I might be interested in, instead. Also this is awful at xmas time because it gives away what I have bought as gifts for the family!
