What you actually need
A training suit ($20-30) is the starting point. A basic nylon one-piece works for any kid under 12. Only jump to a competition tech suit ($50-150) if your child is 12 or older and swimming competitively year-round. The performance gains are real at that level, but younger swimmers don’t need it.
Goggles with anti-fog coating ($15-25) make the difference between liking and hating practice. Invest in something decent here—$8 goggles fog constantly and kill enthusiasm. A swim cap ($3-5) keeps hair out of the way and is practically free. A good towel is mandatory, but any standard bath towel works fine.
That’s it. Four items, under $80. This is genuinely the cheapest sport to get started in.

Used gear notes
Used suits and caps are fine from Facebook Marketplace or Play It Again Sports. Goggles should be new—used ones have scratches and dead seals that defeat the whole purpose. Always buy new.
What you can skip
Skip premium tech suits until your child is older and committed. Skip the fancy $40 warm-up jacket—a regular sweatshirt works. Skip multiple caps. One is plenty. Skip the equipment bag. A grocery bag works fine.
