DH and I had a relatively low budget wedding and it was lovely.....here's how I saved money --
Since you're still in the US, check out
www.bridesave.com for your dress. I bought my dress from them and saved quite a lot over what they wanted in the bridal salon. The cheapest thing to do is look for a white or ivory bridesmaid dress as they're rarely more than $300 or so. Bridesave lets you search by colour, length, size, fabric, etc., so it's a really quick way to find what you want.
Flowers -- go artificial. I know some think it's tacky, but whatever...I still have my bouquet and love it. I went to a local pottery and bought a ton of flowers for about $70 -- enough to do my bouquet, 2 bridesmaid bouquets, 3 corsages, 7 bouts, decorations for the head table, and the altar. If you're even remotely crafty, you can arrange the flowers and make the bouquets/corsages/bouts yourself.
Invitations -- I bought nice paper and nice hydrangea stamps and inks and made all of our paper goods (invitations, save the dates, response cards, menus, programs) on the computer. I probably spent about $20 total.
Bridemaid gifts/jewelery --
www.bluemud.com As part of their gifts, I gave my bridesmaids, mom, and grandmother silver charm bracelets that I assembled using the charms and bracelets from this site. The prices are fantastic, and so is the quality and service.
Hair and makeup -- did it myself.
Tiara -- made it myself with a cheap headband, some gold wire, and glass beads. It took a couple of hours and cost about $20.
Church -- we were married in the church my family has attended for years and years. Since my parents and grandparents are members, we could use the church for about $50, which included the sound technician.
Music (church) -- I burned CDs of the ceremony music...the sound tech just let them go. Sounded great and cost nothing!
Reception venue -- Think about the organisations your family/fiance's family work with/belong to and see if you can use their venue for free or for a reduced rate. My stepdad was in the military so we were able to hold the reception at the officer's club, which was nicer but less expensive than the hotels in town. I think the total cost for the hall, the food, and the alcohol was about $2000.
Cake -- seek out a hidden talent. We found our cake lady through word of mouth. The cake was lovely, yummy, and cost about $200. I baked the groom's cake (trad English fruitcake) myself. That cost about $100, due to the expensive ingredients, alcohol, marzipan, etc.
Would it be an option for you to get married in the US? In my opinion, it's much easier to do a wedding on a budget in the US. Have a cheap wedding there, then a nice reception here once you're settled.
