Julian, you aretoo sweet! wow! after you give her her gifts, you should show her this thread so she can see how much work you put inot her day!!
ok, as soon as I read your very first post I instantly thought Wrap Dress!! & as I've read through the rest of the thread, I have to say, I am even more certain now. Wrap dresses are very vesatile in sizing, generally you can go up or down a size in the same dress, so you won't have to be too precious about getting her size/shape exactly right. also, they are extremely flattering & very chic, so she won't feel over or under dressed for the restaurant you tak her too.
one owrd of warming, for the spa, don't get her a treatment likea facial, they need a good day or longer to settle down before a big event cos your face goes blotchy & red, so I'd go for a fabulous aromatherapy massage, or a body mask treatment, somethign like that, but nothing on her face. of course, a mani & pdi is always very satisfying too
totally with the others about the shoes!! those black ones she has are fine!!! (cute actually
) I would def spend the money on a fab bag or maybe an extra treatment at the spa.
would also go for a clutch, have you considered vintage? if you have any great vintage or charity shops near you you could take a quick browse.
I can't help at all on personal recommndations for meals or restaurants but I'm going to NY in a couple of weeks & so have been asking round on here for suggestions, if you do a search you should find some fabulous suggestions! Pastis & Balthazar seem to be firm favourites
This maybe a ridiculously touristy thing to do but what abot uone of the river cruises? I read of one that has a great 3 course meal on it included. that might be a memorable thing to do?
Whatever you decide, good luck with it, tell us all about it & post lots of pics!!
