2 weddings, 1 maternity dress

[AGnu]

I've got 2 weddings to go to this year, one when I'll be 14w DC3 & will definitely have a small bump & the other I'll be about 37w. Can it be done in 1 dress? I hate shopping. I have up to £100 to spend & I really don't want to wear a tent! I've been looking at Isabella Oliver but the only ones I can find on there that I like are black & I don't want to wear black to a wedding if I can avoid it!

Help?!

Would a 'combination'/'converter' dress suit? I don't know the correct name but they are a dress that converts into several different styles by tying the straps different ways.

There are always some great, barely-worn, occasion maternity dresses on eBay - for example this silk Tiffany Rose dress.
