How to Choose between Opal & Opal Curve

How to choose between Opal & Opal Curve

If you find yourself in the crossover 14-20 sizes and are struggling to choose between the Opal & Opal Curve patterns, today I will be sharing a visual comparison between them! Our diagrams will compare a size 18 from our 0-20 range shown in the outline to the size 18 in the Curve range as shown in beige.

Opal & Opal Curve drafting comparison

As with all of our patterns, the Opal Curve pattern is drafted with the same style and design details but with a curvy figure in mind. This pattern has a generous amount of ease and a very comfortable fit without being too baggy.

Curve sizes 14-30 are drafted with a more scooped-out crotch curve, slightly more ease, inner leg room and a deeper rise.

If you have any questions on fit or sizing we are always here to help! Pop a comment below or email us at to ask any questions!

Hi Mimi!

That’s a great question! Though it appears that way because we aligned the pattern pieces at the hem, the rise is not lower on the curvy range – it’s actually slightly deeper :) The inseam length is shorter in the curve pattern, and as we aligned the pattern pieces on the hem, it has made it appear as if the rise is lower. To be honest, that is a presentation error on my part and i should have shown the diagram more clearly. I hope that helps!
