Don't get too excited about Hobbs yet as they've only made six items, but it's a start, so maybe if this goes well then they might expand their range. There've been far too many shops in the past who made petites but then stopped because they didn't advertise it so nobody knew about it, so I'm just spreading the word!

It looks like the Seasalt petites must've been going for a good few months though as they have a lot more stuff, but I only found it when I did a general Google search for petite clothing, which I don't usually do as I tend to know which shops make petites. Why haven't Seasalt advertised this properly?

Has anyone else here had an "I didn't realise they made petites" moment with any other shops recently?
