I bought this pattern with a view to make it out of knit fabric and I am not disappointed. It is one of the comfiest bras I’ve made now I’ve tweaked the pattern just for me. I’ve made 4 so far, two toiles and two just perfect. I can’t recommend this pattern enough whether it’s made as it should be or in knit fabric like mine. Super glad I purchased it and can’t wait to make more!
I’ve made bras in the past and they have never fit properly. My first make of the Lofus Bra is my new favorite and I immediately bought more kits!
First time sewing a bra and it won't be my last. I was worried with so many fiddly bits and not much patience with accurate cutting from slippery fabric. Even though all my pieces weren't the same size from left to right, due to my sloppy cutting, the fit was pretty darn good. The next time I will use a rotary cutter and not lift the fabric from the cutting surface, which is how I got my not perfectly sized pieces.
I also used narrower elastic than called for because that is what I had at home. I didn't want to break into my lovely kit to make a toile/muslin. This muslin is now part of my regular stash and I plan to make a "real" version this weekend. It's so comfy and there's nary an underwire to poke me. I'm so tired of underwire bras where the underwire escapes from the channeling and pokes either under the arm or mid chest. This bra will never have a chance to hurt me!
Ultimately, there are a bunch of fiddly bits, but they go together with patience into a really great bra. I'd recommend trying it.
First - I find the loftus bra extremely comfortable although mine needed lots of adjustments. It gives lots of support without wires. I also made one for a friend who has very large soft breasts and can not find a good commercial bra. For her this pattern was perfect, no changes needed - she mentioned it is the most comfortable bra she ever had. So I would definitely recommend this for somebody who is very large busted.
For myself though, I had to do lots of adjustments as my bust is medium sized, with wider root and round overall with dense tissue. I feel it pushes my breasts down (makes them look droopy) because it has lots of /too much room under the bust point and it is pretty tight/comfortable above the bust point. Horizontally it fits nicely. I had to remove almost an 1" on the vertical at bust level, and change the angle of the straps. I tried a smaller size and that also needed vertical changes. Quite a few people in the (Beginner International Bra Bee) class I took changed the angle of the elastic from 90 to 120 degrees and sew it around so it does not roll up. The angle of the center cup section is not continuing the center section angle, so I shaved some of the pattern to make it continuous. With these changes, my #4 bra is finally comfortable. I can probably tweak it a bit more but it works :)
I purchased a kit from your recommended supplier in NZ and used the video as I haven’t made a bra before. That all made it so straight forward. The bra fitted perfectly and is very comfortable. I am definitely going to use the pattern again
I've longed for a no-wire bra that also is comfortable and gives plenty of support. This is it! I was a bit hesitant to tackle making a bra, but the instructions were really clear. Thanks a million for having devised the pattern, Jenny.
