A sister style is the same cut, or a very similar one, offered in a different version: a large or ultra petite cap size, a different cap construction such as basic cap, mono part, mono top, double mono top or hand tied, or a different fiber such as synthetic, heat friendly synthetic or human hair. Sister styles let you keep a look you love while changing fit, comfort, styling flexibility or budget.

All three are collections from Rene of Paris. At Wig Studio 1, our 43 Noriko styles are mostly basic cap (32), mono part (9), mono top (2). Our 25 Amore styles lean toward upgraded caps: double mono top (10), mono top (9), hand tied (6). Our 80 Rene of Paris styles cover the widest range, mostly basic cap (36), mono part (34), mono top (6), and include 38 heat friendly styles.

Large caps: Reese Large and Sky Large. Ultra petite (children's) caps: Addison Ultra Petite, Kensley Ultra Petite and Miley Ultra Petite.

Angelica by Noriko comes as Angelica (basic cap) and Angelica PM (mono part). Scorpio by Rene of Paris comes as Scorpio (basic cap) and Scorpio PM (lace front with a mono part). PM stands for partial monofilament.

Human hair styles include Alina, Brielle, Darra, Harriet, Kris, Lily, Oakly, Olivia, Payton and Thea.

A basic cap uses machine-made wefts and is the most lightweight and budget-friendly. A mono part adds a sheer monofilament strip where the part is hand-tied, so it looks like it grows from the scalp. A mono top extends that across the crown, and a double mono top adds a second soft layer for sensitive scalps. A hand-tied cap has every hair knotted by hand for the most natural movement and the softest fit.

Yes. Every style in this guide shows the closest Jon Renau and Raquel Welch looks and how they differ, such as a lace front, hand-tied cap or heat friendly fiber. Tap one to open it in that brand's sister styles guide.
