What to wear to Caribean wedding for the mother-of-the-bride?

I would be taking some clues from the attire of the wedding party. What are they wearing? Also, this is a great time to reach out to the other mother and use your "what to wear" question as a means of getting to know her a little better. After all, she is in the same boat as you are with this question. Bealls is a department store that caters to the Florida lifestyle, so you might find a more tropical selection there. Just a few quick thoughts that I hope are helpful.

I would go for a sleeveless knee length flowy beachy style, something comfortable but semiformal.

I would try most department store websites, saks 5th ave., dilliards, jc pennys, and www.forever21.com, it's designed for juniors but has conservative dressy peices you could put together to look updated to surprise your daughter :]

I agree with s3ndt3hn00dzz, as soon as I saw your post I was thinking the same thing.
Is it going to be daylight or evening?
If it is daylight I would recommend either for lighter hair, a beachy style dress,light material, kind of like a coverup but like light material or sheer material with a satin or sil or lightbut not seethrough material backing.Nothing really extravagant(unless wedding is kind of formal)with beading, no sequins, maybe neutral beads that compliment the colour of the dress, which in my opinion on lighter blondes should either be turquoise or brown, and for brunettes turq, purple, rasberry pinks and magentas.As for shoes it really depends on the place, like a if it is at the beach,sandals, with beading(NO SEQUINS)
.If it ia at a hotle or indoors, don't go crazy with heels(like I am going to tell you I seriously doubt 6 inch heels are going to look good with this kind of dress I recoomending.

If it is at night then I would recommend a lighter spectrum of colours, but still the same advice on the colours.
Since it is CArribean I wouldn't recommend you wear tighter clothes(dresses)If you find a dress that is not wispy but is kind of suiting, maybe wear a shrug or crop jacket with it.Layered bead necklaces are good, but no more than 2 and if you are older than I would recommend the thinner beads, nothing chunky because it will look like you are trying to be hip and funky, maybe a bracelet.

I hope all goes well and I helped.

Ohh!And if it is really hot and the wedding is outside then maybe a plain straw hat(not tourist like with baggyufloral shorts and cameras, but think just a flowy type one, like the ones that have flowers or feathers, but 86 the over accesories)
