Methodology
Last updated
Each business is rated 1–5 on five factors. The weighted total is scaled to 100.
| Factor | Weight | What we look at |
|---|---|---|
| Selection | 30% | Breadth and depth of stock, and how well the store covers its specialty |
| Price / value | 15% | Posted prices, wholesale options, and what reviewers say about price. Neutral 3 when there is no evidence. |
| Reviews | 25% | Public star rating weighted by review volume. A small base caps the score at 3–4; no independent reviews means 1. Reviews that read as templated count for less. |
| Service | 15% | Recurring reviewer themes about staff help, samples, shipping and responsiveness. Neutral 3 when there is no evidence. |
| Accessibility | 15% | Days and hours open, parking, location, online ordering and shipping |
Same weights, category-specific labels
Every category uses the same five weights. What each factor measures is adapted to the category:
| Weight | Fabric stores | Tailors & alterations | Sewing classes | Dry cleaners | Shoe repair | Upholstery |
|---|---|---|---|---|---|---|
| 30% | Selection | Services range (suits, bridal, leather, designer, custom, rush) | Class range (levels, techniques, kids/adults, open studio) | Services range (cleaning, laundry, alterations, gowns, leather, pickup) | Repair range (resoles, heels, dyeing, boots, handbags, luggage) | Work range (sofas, chairs, cushions, slipcovers, custom pieces) |
| 15% | Price / value | Price / value (published or reviewer-reported prices; neutral 3 if none) | Price / value (posted class prices, materials included; neutral 3 if none) | Price / value (neutral 3 if none) | Price / value (neutral 3 if none) | Price / value (quotes reviewers report; neutral 3 if none) |
| 25% | Reviews | Reviews | Reviews (a studio inside a store is rated on the store's reviews, and we say so) | Reviews | Reviews | Reviews |
| 15% | Service | Service (turnaround, reliability, care with garments) | Teaching (patience, clarity, class size, per reviews) | Garment care (stains, damage, reliability) | Craftsmanship (quality and durability of work) | Craftsmanship (fit, finish, honest advice) |
| 15% | Access | Access (days/hours open, parking, location) | Access (schedule breadth, evenings/weekends, location) | Access (hours, Sundays, pickup/delivery) | Access (days/hours open, location) | Access (hours, pickup/delivery) |
Review score guide: 5 = 4.7★+ from 150+ reviews; 4 = 4.5★+ from 40+ reviews; 3 = a small base (under about 40) or 4.3–4.4★; 2 = under 15 reviews or conflicting ratings between sources; 1 = no independent reviews.
Editorial order
As of October 29, 2026, the fabric and tailor lists use editorial order. KBM Fabrics is #1 and Quilt Emporium #4 in fabrics; Dorcas Tailor Shop is #3 in tailors. Editorial order is separate from the weighted scores. KBM was reassessed to 77/100 on October 29 using updated catalog and access information from its official FAQ; the other scores remain unchanged. Other categories retain their existing order.
Countywide coverage
Rankings cover all of Los Angeles County. We group businesses into regions (Downtown, Central LA, Westside, San Fernando Valley, Northeast LA, San Gabriel Valley, Gateway Cities, South Bay, Long Beach, Santa Clarita/Antelope Valley) so readers can find nearby options. A region with no verified store is shown as empty rather than padded.
Rules
- We never invent ratings, addresses, hours or quotes. Anything we couldn't verify is marked unknown or credited to the listing it came from.
- Review counts name their source and the date we checked. These numbers change daily.
- No business can buy a score or a rank. Fabric and tailor lists use the editorial order explained below.
- No business gets a different rubric. We do not use other publishers' sponsored placements (for example their “Featured Partner” labels) when we score a shop.
- Ties are broken by review volume. Closed businesses are listed separately and never ranked.
Corrections
We fix factual errors (addresses, hours, closures, ratings) as soon as we confirm them. Every correction is dated and described on the page where it appears, and the “Last updated” date changes with it.
