Hi sweets,

I think Mat shops are prob your best option given how far along you will be at the wedding. I have seen a couple of nice dresses in Egg Maternity (retail about 300-500).

As far as the day of the week is concerned, if people want to come, then they will regardless. If someone I knew and liked was having a wedding, Id go even if it was at 4am!

Inside or out - can you leave it till the week before the wedding? Then you can check 7 day forecast and decide.

As for the MIL - go for your life, you can beat mine too while your at it
