The Online-Sizing-Challenge Case

Why online activewear sizing is hard: the the-cant-try-it-on (the online = cant-try-it-on from the activewear-online-shopping chapter — the the-cant-try; the the-guessing; the the-the-challenge), the the-brands-size-differently (the brands-all-sizing-differently — the the-varies; the the-inconsistent; the the-vanity-sizing), the the-wrong-guess-costs (the a-wrong-guess = returns-or-unworn-pieces — the the-wrong-guess; the the-returns; the the-drawer-of-unworn), the the-fit-is-crucial-for-activewear (the fit-mattering-a-lot for activewear-function — the the-fit-matters; the the-function; the the-crucial), the the-getting-it-right-is-a-skill (the sizing-right being a-learnable-skill — the the-skill; the the-learnable), and the reframe (the online-sizing as a learnable-skill for low-risk-online-shopping — the nail-the-size; the the-no-return-nightmare).

The How-to-Get-the-Size-Right Method

Getting your online size right: the the-measure-yourself (the measure-yourself (waist, hip, bust) — the the-measure; the the-your-numbers; the the-the-key), the the-use-the-brand-size-chart (the shop-the-brand’s-size-chart (not-your-usual-size) — the the-size-chart; the the-brand-specific; the the-not-your-usual), the the-read-reviews-for-fit (the read-reviews-for-fit (‘runs-small’, etc) from the activewear-review-reading chapter — the the-reviews; the the-fit-feedback; the the-crowdsourced), the the-check-fabric-and-stretch (the check fabric-and-stretch (forgiving-or-not) from the activewear-fabric-tech-decoder chapter — the the-fabric; the the-stretch; the the-forgiving), the the-between-sizes-strategy (the between-sizes: size-by-intent (compression-vs-comfort) from the between-sizes logic — the the-between-sizes; the the-by-intent), the the-know-your-fit-preferences (the know-your fit-preferences — the the-preferences; the the-your-fit), the the-check-the-model-info (the check model-size-and-fit-info if-given — the the-model-info; the the-reference), and the the-test-quality-on-arrival (the test-quality on-arrival from the how-to-test-activewear-quality chapter — the the-test-quality; the the-check-it).

How it works

The Smart-Return-Strategy Notes

The low-risk return strategy: the the-buy-from-easy-returns (the buy-from-easy-return retailers — the the-returns; the the-easy-returns; the the-safety-net), the the-order-two-sizes-if-unsure (the order-two-sizes, return-one — the the-two-sizes; the the-return-one; the the-guarantee-fit), the the-check-the-return-policy (the check-the-return-policy first — the the-policy; the the-know-it), the the-keep-tags-and-test-inside (the keep-tags, test-fit-indoors from the how-to-test-activewear-quality chapter — the the-tags; the the-test-indoors; the the-return-if-not-right), the the-squat-test-before-removing-tags (the squat-test with-tags-on — the the-squat-test; the the-tags-on; the the-check-opacity), the the-note-what-fits (the note brands-and-sizes-that-fit for-next-time — the the-note; the the-learn; the the-next-time), the the-dupes-vs-originals-note (the dupes-vs-originals from the dupes-vs-originals chapter — the the-dupes; the the-value), and the frame (online activewear sizing through the online-sizing-challenge-case, the how-to-get-the-size-right and smart-return-strategy — the measure-yourself, shop-the-chart and read-reviews plus easy-returns that make online-shopping low-risk; the sizing, nailed). Buying activewear online means guessing your size across brands that all size differently, and a wrong guess means returns or a drawer of unworn pieces. Nail it: measure yourself (waist, hip, bust) and shop the BRAND’S size chart (not your usual size), read reviews for fit (‘runs small’), check the fabric-and-stretch, and size by intent when between sizes. Then de-risk it: buy from easy-return retailers, order two sizes if unsure, keep the tags and squat-test indoors before removing them, and note what fits for next time. No return nightmare.
