I don't think they serve no purpose. ...
So what is it? That's all I'm asking...
You are explaining why LH uses S/M/L sizing for its products but I totally understand, I do the same thing. I do not understand why a manufacturer would install an expensive feature that makes it more difficult to sell an item!
^^ It doesn't make it more difficult to sell them... I'm a bit confused as to where you've got this information from, Talia.
We sell more basques than almost any other style of lingerie, and basques have one of the lowest returns rates too, so most people love the overall design.
It sounds to me as though basques may just not be the right garment for you. After all, not all products work for all people. Personally, I hate triangle bras on me: the do nothing to flatter or support my chest. This doesn't mean that the design of the product is bad - they work for millions of other women. It just means that they don't work for me. Therefore, I shop for something different.
The purposes they serve are (as you said yourself) boning helps to keep the material in place, particularly when worn without stockings. As well as this they add structure to the garment and create a different sensation for the wearer which feels more restrictive than loose lingerie, without being as restrictive as a corset.
My recommentation would be for you to browse some different lingerie styles to find something which you do like. The fact of the matter is, basques have remained unchanged for many, many years, and sales are fantastic, which tells us (as a business) that the design works. I'm sure you can appreciate that if we changed the design of a product every time a customer told us they didn't like something about it, we would never sell anything! "If it ain't broke, don't fix it!"
The good news is there are many different styles of lingerie available to suit all tastes and preferences. If you're not a fan of plastic bones, maybe you should check out fitted chemises instead?
