European Kids Clothing Size Guide (Singapore Edition): Jacadi, Petit Bateau, and Jamie Kay vs. Uniqlo
Shopping for pre-loved European kids’ clothes can be tricky. A “3 Year” tag from a French designer fits very differently than a “3 Year” tag from Uniqlo or Cotton On.
At Viktor & Sasha, we inspect thousands of garments. We know that French brands often run smaller and slimmer than the standard Asian sizing you might be used to. To help you pick the right size for your little one, we’ve created this comparison guide specifically for Singaporean parents.

Detailed Sizing Breakdown by Brand:
Jacadi: French sizing is based strictly on height. Jacadi cuts are elegant and slim. For pre-loved items, we recommend buying one size larger than your child’s current age.

Browse our selection of pre-loved Petit Bateau itemsJamie Kay: Uses standard international sizing but relies heavily on organic cottons which can shrink in hot washes. Our pre-loved Jamie Kay items are measured to ensure they haven’t shrunk below the 1-2cm tolerance.
Browse our selection of pre-loved Jamie Kay itemsRalph Lauren: Uses American sizing (US), which is generally wider and boxier. A Ralph Lauren “2T” will often fit a child longer than a Jacadi “2A”

FAQ
Q: Is Jacadi sizing small compared to Uniqlo? A: Yes. Jacadi is cut slimmer than Uniqlo. A Jacadi 3A is designed for a child up to 96cm, whereas a Uniqlo 100 (3-4Y) fits up to 105cm. We recommend sizing up one year for Jacadi.
Q: How do I know if pre-loved clothes have shrunk? A: At Viktor & Sasha, we re-measure garments if they appear altered. However, high-quality European cottons (like Petit Bateau) are designed to hold their shape better than fast-fashion alternatives.
Q: What does “3A” mean on a French label? A: “3A” stands for 3 Ans (3 Years). In height terms, this usually corresponds to roughly 94-96cm, which is smaller than the UK/US standard of 98-100cm for age 3.
