What's happened to my knees?

I had a fruitless search through the local preggie-wear shop for a light summer dress - there's a summer sale on but of course if it's in my size then either I don't want it or someone else just bought the last one. I also went into one of the large second-hand clothes shops, but no luck there either. Second-hand shopping really takes a lot more patience than I ever have when I'm looking for something in particular.

In this kind of heat, and with this much difficulty in finding something that fits right and doesn't make me look like one of Trinny and Susannah's fashion criminals, it's no wonder that some women resort to tents and kaftans. I can almost feel the desperation coming on.

Hopefully my brother's partner will have some preggie gear saved by which I can borrow. She's a different height and a different colouring, but most preggie stuff I've seen is black anyway and I can just promise not to shorten anything permanently (she has enough three-quarter length pants).

In the meantime I finally found an old sundress which I bought years ago. It's too short really, but it's cool to wear and should be fine as long as I don't wear it out in public. I really don't remember my knees looking quite to pudgy in it though. I sincerely hope that, whether it's fat or water retention, it's temporary.
