String Side Bikini Bottom

A Little Change goes A Long Way

From a simple band side bikini bottom, it's not big jump to convert it to a string side. I have always preferred to create my string sides from band sides rather than go back to the block. I feel I get a better perspective and continuity with other designs in a collection, but it's entirely choice. This technique will be based on the band side bikini bottom we made previously. Here's a few examples of string side styles: wide to narrow in front, then wide to narrow back ... you can mix and match pretty much any front with any back!

Take a look at the illustration below. You will notice I've drawn a line perpendicular to each side seam that extends to the centre (black dotted lines). This represents the direction the strings will apply tension to the garment. You can place them anywhere along the side seam, they are arbitrary, just place them in the same position at each corner and stay perpendicular. I've chosen the centre of the side seam. You could choose the top if you want a slightly more conservative approach (surfwear) or the bottom if you want a little more risqué (high fashion). This few centimetres does proportionally make quite a difference to your start position.

The next question is where to place corners of your garment. You really need to stay as close to the back side seam as possible in for the back panel. On a string side bottom, the string position is usually biased towards the front in order to allow as much bottom coverage as possible. This means that the front corners are positioned 4-5cm inside the side seam.


Of course it really all depends on what you are trying to create. Remember that, just like the band side, as the pattern gets narrower it tends to stretch more and lose its rebound strength. Another consequence of narrowing the back panel is that it begins to drop between the cheeks rather than sitting out over them. This means you will need to shorten the pattern a little.


The various coloured lines represent the limitless design possibilities. All are valid. The green and yellow lines are the current Brazilian style. This style is not very stable, but that's hardly the point of the garment. The purple line represents the back crotch of the G-string. No matter what top style you use on the G-string, this is the back that covers all the essential bits and shouldn't be changed for anatomical reasons. That said, there are manufacturers out there making even smaller pieces called 'microkinis'.


This all goes to show you can pretty much do anything you want ... including adding a CB seam as in the next bottom style being demonstrated. Be mindful that these same concepts do not directly apply to one piece swimsuits.
