valz - I have them - just on my sides around my hips, thankfully, but they're there. I was 23 weeks as of yesterday.
Re: maternity clothes, I'm lucky in that it's jeans and t-shirts for work, so I stocked up on M&S jeans (so far so good), H&M tops, New Look tops, and some Mamas and Papas very nice tops (I signed up for a catalogue online and got a £5 off gift token to use). I've also got a belly belt, which has allowed me to wear my last two pairs of normal jeans a bit longer (I've always been a waist kind of girl rather than hipsters), although I think I'll need to get some braces in the next month or so to keep them up (I'm on the last notch of my belt). I've also got bump bands to cover up that open zip area, but they're still a bit too big for me.
I saw that UniQlo had some vests new in-store which have a built in bra (no wires), although they don't come in XL (I might fit a L though!) - thought I'd mention it anyway, if anyone likes that kind of thing, post-pregnancy? They look quite comfy for sleeping in, anyway. www.uniqlo.co.uk/catalogue/women/t-shirts-and-polos/361945-black-bra-tank-top
Incidentally , if anyone is around the SE and London, and has a 'Cook' store near them, they do a deal for pregnant ladies - valid only for six months, but hey. Basically, sign up (it costs nothing), you get 10% off your total food shopping (could be handy once the big day comes, but there's time to send someone else to get some food for you (who has to be named on your card - it can only be one other person)), and as well as that, you get a loyalty card, which is stamped for each £5 you spend - once that's full, you can have £10 of free food. Oh, and although it says "Frozen Ready Meals" we're talking nice frozen ready meals...! www.cookfood.net/
