Need sizing help

http://www.lovehoney.co.uk/product.cfm?p=32057

I'm looking at getting this for my OH, the problem is she wears a 8 to 10 in clothes and underwear. I'm not sure whether to go for the medium or small.

Have any of you got this piece and have any advice?

Thanks

Do you know the fit of her clothes? Say, does she normally wear size 10 if the clothes are quite weill fitting and size 8 if they're a bit looser? If she does, then I'd go with the M. Otherwise maybe the S!

I'd probably size up. The chemise can be adjusted to fit perfectly and will save having to send it back if it doesn't fit :)

I was too late, they took it out of the sale.

This sale is a Whirlwind. Managed to get the medium ordered. Lucky for me I came home and the missus had greeted me in a nice chemise with matching thong, shame it isn't the new one yet but this was a nice surprise. Should be a fun night.
