We recommend a separating invisible zipper for this garment. Using a separating zipper will make it easier for you to take the top on and off.
##### When making Tristan with the lacing option, reinforce the eyelets
When making Tristan with the lacing option, make sure you reinforce the eyelets. A binding, or sewn in interfacing could work to do so. Adding boning between the eyelets and the seam is another option.
Tristan is not a corset, and therefore doesn't require heavy boning. We would recommend using a flexible type of boning. That would create the neatest opening. Otherwise a double layer of hair canvas and put the eyelets close to the seam. Both would require lining, or an adequately sized hem or binding.
