Has anyone had a problem when adding the crotch piece to a swimsuit bottom? If I omit the crotch piece the bottoms fit really well, when I add the piece the bottoms become too big. I noticed on the one piece suits there is no crotch piece. When making many leotards there was not a crotch piece and they fit really well but my oldest grandaughter said it's not as comfortable. Any suggestions would be greatly appreciated. Thanks
