Lastly, scrunch the front crew with the desired fullness and shape. Tie off to preserve the curve and finally, knot the ends.
My guy gifted me this hand-painted T shirt from recent travels with the inherent challenge - that I make it wearable. Follow these instructions and you can turn any ill-fitting souvenir T into a cute slouchy halter top you'll wear all summer. You'll need thread, a sewing machine with at least zig-zag, an overlock is better, 1/4 yard of contrasting knit fabric or another T shirt of complimentary color, a large safety pin, the usual scissors and pins, and a dress form or warm body to fit.
Lay the T shirt flat on your work surface with the body aligned as straight as you can, with the design you like best facing front.
Step 2: Styling the halter front by making some choice cuts.
Measure 4" out from the edge of the Crew band on either side and mark with a pin.
Using a straight edge, draw a line down at an angle from this point shearing off the sleeve and armscye (that's the sleeve seam). Cut along this line.
Step 3: The Patterning Reverse and Repeat Trick
I like to take the sleeve I just cut and flip it and align it over the top of the other, uncut sleeve, matching edges as best I can. Then, I use a straight edge and transfer the cut line with a pencil. Cut off the other sleeve along this line, so they angles match as closely as possible.
Step 4: Slice the Shoulders
Cut the shoulder seam on both sides, and trim the old seam away completely from both new edges.
Step 5: Halter and Yoke
Take your contrasting fabric and other T shirt. This works best if you use a slightly bigger T than your halter. Slice off the bottom contrasting T at 4" from the bottom or cut a 4" band from another knit fabric, at least 2 inches longer than the circumference of the halter T bottom. Cut another 1" strip from the body of the contrast T or fabric, a yard long. You'll need to cut this so it rolls upon itself, making a tube, so work your warp and weft to optimize the curl.
