In reply to Hooo:
Same - I bought that same harness in the same size as a gift for MrS a few years ago and it was massive.
Sizing in womens clothing is very unreliable and erratic. Even if you go buy the size charts and take body measurements (which you shouldn’t have to - surely the point of having a numerical size is that it’ll always fit those measurements) the size of the garment is often way off. I have even found two apparently identical garments, same size, same label, same item, to be very different in size.
Whilst I can see that different brands leaning towards slightly different fittings can be a good thing as there are so many variations in body shape within a size bracket, vanity sizing is a total pain, particularly for smaller sized people who can’t size down as they are already wearing the smallest size.
To add my own grump about women’s outdoor clothing - they could do with making the armholes/sleeves/shoulders a bit more accommodating. Bearing in mind that some of the users might be active people who have some muscle on their arms (North Face I’m looking at you with your very narrow sleeves).
