How can I make sure my bridesmaids gowns are the best fit possible?
Make sure your bridesmaids get measured properly. If in question, measure twice.
The most common mistake is that bridesmaids measure too far down for their waist measurement. The waist is measured at the smallest part of the torso, above the belly button - not where you wear your jeans.
Your bust measurement is not the same as your bra size.
Follow the size chart provided on the back side of your bridesmaids sheet. Every bridesmaid's gown designer has its own size chart, and the sizes can vary greatly. You could wear a 6 by one designer and a 10 by another designer.
Do not guess at your size. You can always have a gown taken up but you may not have enough fabric to let a gown out.
Bridesmaids gowns are not cut to personal measurements. You are ordering the closest size to your measurements.
