Just perfect!

If you would have asked me a couple of months ago if I would sew my own underwear, I would have laughed out loud!
Enter, the Radcliffe. I have made 4 pairs and really don’t see myself buying RTW undies ever again.
This pattern, and instructions, make sewing a basic item, easy and fun.
The options are endless and I now keep my eyes open for leftover scraps to be set aside for this pattern!
I’m so very glad to have Radcliffe.
And incidentally, this is my first, of many CASHMERETTE patterns, to sew.

Undies, Undies, undies!

All I can say is WOW! The Radcliffe undies are FABULOUS!. My first pair took about an hour to make, ..learning curve. I made 6 more pairs the next day after wearing the first pair for comfort. And they were very comfortable!
I love not having side seams.
I found several ways to apply the elastic, and used several types of elastic. That's the beauty of Sewing, isn't it? My shape is outside the parameters of the pattern by quite a few inches, and altering the pattern was quite simple.
Give them a try, they are wonderful!

Wonderful Undie Pattern for a Beginner Sewists!

I just finished making my very first pair of undies, and I couldn't be happier! As a beginner to this type of project, I found the written instructions incredibly detailed and easy to follow.

What really made the experience seamless was the fantastic YouTube sew-along by Whitney of TomKat Stitchery—having that visual guide alongside the pattern was a total game-changer. I also really appreciate the variety of views included in the pattern because now that I have my first pair down, I am ready to make many more!

love the coverage

as I get really into lingerie sewing, I've tried a few undie patterns from a few different places and this one is my favorite for the full coverage rear and generous gusset. I went slightly up in size because I prefer a softer fit and I took a bit off the front and crotch seam allowances and I've already adapted the pattern for different looks. If you like a full coverage rear but also cute undies, this is the pattern for you.

I made already seven undies ( high waist with elastic lace at the top) out of microfiber. They fit perfectly, I love the pattern and the fit. Thank you Cashmerette Team!
