The Zoe leotard has retro appeal with a colour-block empire waistband and v-neckline.
Yumikoleotards run a little small, but with a little stretch in the straps of the camisole styles. Sizing preferences depend on how tight you would like the straps or how high you would like the neck line.
A small Yumiko is similar to a Ballet Rosa XS, laying flat (no stretch).
An XS Yumiko will fit children in a Ballet Rosa 12, laying flat (no stretch).
