How many weeks before the wedding should you start dress alterations?

Begin your dress alterations about 8 to 12 weeks before the wedding. This gives your seamstress or tailor enough time to make structural changes, like taking in the bodice or adjusting the hem, and to do a second or third fitting. Most dresses need at least two fittings, sometimes three, so starting too late can mean rushed work or a poor fit. If you are planning to lose weight or if you are between sizes, start earlier, around 12 to 14 weeks before, so your seamstress can plan for changes.

At your first fitting, wear the underwear, shoes and any shapewear you plan to wear on the day. Bring along any accessories like a veil or jacket, so the alterations can be planned around them. Be clear about how you want the dress to fit, snug but comfortable, and remember that you will be sitting, dancing and eating in it. After the first fitting, your seamstress will pin the dress and note any changes. The second fitting, usually 4 to 6 weeks before, is for checking the adjustments and making fine tweaks. The final fitting should be about 1 to 2 weeks before the wedding, so any last-minute weight changes or shoe adjustments can be handled.

Always leave a little extra fabric from the hem in case you need a small repair on the day. And keep your seamstress's contact details handy in case of any last-minute issues.
