She is the best seamstress in Houston!
I arranged to have their seamstress sew you one.
A seamstress can easily create a suitable modesty panel to wear beneath an immodest dress.
If you are a seamstress, you may want to make your own dress to get exactly the look you want.
This way she could save money and in any case, she considered herself a better seamstress than any professional upholsterer.
