Tiny Trench Coats and Mini Blazers: Adult Classics, Kid-Sized

1. Grown-Up Classics, Made Small

The trench coat and the blazer have been staples of adult wardrobes for decades. Now they're showing up in kids' fashion too, and they suit little ones better than you'd expect. Here's how to wear them, with a few One Friday picks.

2. Start With the Trench Coat

Throw a kids' trench coat over a plain tee and jeans, or over a party dress, and the whole outfit looks more thought-out. Stone, camel and khaki are the classic shades. They also hide a muddy splash better than most kids' coats.

3. Small Details Make a Big Difference

Check the buttons first, because a child should be able to do them without help. Then look at the sleeves, which need room for a sweater underneath, and at the lining, which should feel soft against the skin. A tie belt is a nice touch, though a coat that hangs open looks just as good.

4. Boys' Blazers, Minus the Stiffness

The best boys' blazers are unstructured and lightly lined, so they move when a kid does. Navy, olive and oatmeal work with almost everything. Wear one over a crisp shirt for a family function, or over a plain tee and chinos for something more relaxed.

5. Girls' Blazers Work Just as Hard

A girls' blazer in a soft check or a solid pastel looks lovely over a summer dress, and it's equally at home with a skirt or straight trousers. Go for a slightly relaxed cut, since a fitted one tends to get outgrown by the next season.

6. Keep Everything Else Easy

With a statement layer on top, the rest of the outfit stays simple. A plain tee, comfortable trousers and sneakers are plenty. The polish comes from the jacket, and the sneakers keep it playful, so it still feels like kids' wear.

7. One Layer, Many Occasions

The same blazer that goes to a birthday party can turn up at a wedding lunch and in the family photo afterwards. A trench coat covers rainy days, cool evenings and the odd over-air-conditioned restaurant. Few kids' jackets get that much use.
