How to make a triangle top swimsuit pattern. 

Hello Krosettedesigns, For double letter you could add 5mm or 1/4 inch. After D cup I would also add 1 cm or 3/8 inch to all other measurements I gave, except for the last 1.5 cm or 5/8 inch hem/tunnel. So top (1 cm would be 2 cm or 3/8 is 3/4 inch) bottom (1,5 cm would be 2.5 cm or or 5/8 is 1 inch) side add on (3 cm would be 4 cm or 1 1/8 is 1 1/2 inch) Side curve (1.7 cm would be 2.7 cm or 5/8 is 1 inch) and (bottom curve 1.5 cm would be 2.5 cm or 5/8 is 1 inch) . DD = 10 cm or 4 inch E = 10.5 cm or 4 1/8 inch F = 11.5 cm or 4 1/2 inch G = 12.5 cm or 4 7/8 inch GG = 13 cm or 5 1/8 inch H = 13.5 cm or 5 1/8 inch Than it's for you to try and see if it fit to your taste, It's fast to do. Let me know. Diane

Bonjour Karim, J'ai aussi Ma chaine français ru-vid.com/show-UCaq7zDtYsUkGeI18qFbpTawvideos ou j'ai fais la même vidéo en français. Diane

Hello Cida, yes the t-shirt ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZoieRVAVFGs.html knit sleeve : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pHtKuB_743c.html and a lot more in My channel : ru-vid.com Diane

I think those usually have a dart at the bottom rather than the gathering string, because those gathers would show under your clothes... but the principle would probably be similar. Of course, I'm not Diane and this is just a guess. :-)

Hello Adeejah, yes for sure, and for the rest of the top, I would trace the pattern pieces from the t-shirt block. Diane

Hello Beth, Thanks for your comment in response to Adeejah, Yes, you are right, most of the brallette have a dart or a seam to eliminate the gathers. But, you could use this triangle, to start with, I did it with a 3 cm dart right on the center line using the radius for the dart length, it only need a little correction at the bottom (soft curve & jug) Diane

Thanks a lot ❤️❤️

Thank you so much. I will love to learn from you. Do you have classes? May I have an e-mail address?

Hello@@enukau My e-mail is dianedeziel@gmail.com Unfortunately I don't have classes, some people think I have a team working with me, but I'm by myself, I do everything myself, preparation, PDF, digital pattern, filming and editing the videos in both of my channels (french & english) and I answer questions, even pattern corrections (with picture), here, and in all my other site WIX, ETSY, Gmail, youtube, instagram... That last part takes me at least 2 hours every day. I'm not complaining, I love to have feed back, but it does keep me more than occupied. Diane

@@DianeDezieltoolfully Thank you so much for your hard work to create. I appreciate the lessons.
