6. Araks
Materials: Organic Turkish cotton, Italian crepe
Size & Price: XXXS-XXXL (limited runs) | Starts at $40 (small-batch exclusivity).
Why Artisanal Craft
- Small batches: Araks’ NYC-made pieces are instant collectibles. Limited runs (50–100 units per style) create scarcity—so you can charge premium prices without markdown wars. Think: “Get it before it’s gone” urgency.
- Natural dyes: Their madder root-dyed silk thongs aren’t just undies—they’re wearable art. Share behind-the-scenes reels of dyeing vats or artisan stitching to hook Instagram’s #SlowFashion crowd.
- Silk that bends: Korean-washed silk feels like second skin and survives 50+ gentle cycles. Market to high-end boutiques as “investment lingerie” for clients who value durability and decadence.
- Gym clothing collabs: That Italian cotton crepe? It’s moisture-wicking and buttery-soft. Partner with luxury activewear brands to create custom gym clothing lines—yoga bras or recovery shorts that blur the line between gym and boudoir.
- Trimmings-free: No itchy tags or excess lace. Just clean seams and jewel tones (emerald, plum) that pop under sheer fabrics. Minimalism that maxes out appeal.
7. Knickey (Now Subset)
Materials: 95% GOTS organic cotton, 5% elastane, OEKO-TEX dyes
Size: Women’s XXS-4XL
Recycling is Your New Retention Tool

- Their undies are certified free of endocrine disruptors—a major selling point for wellness boutiques, maternity stores, or allergy-sensitive shoppers. Partner with dermatologists to bundle Subset with skin care products (“Head-to-Toe Health Kits”).
- Offer 3-packs at 33(11/pair) to nudge shoppers toward higher spends. Pro move: Add a free recycled tote with 5+ pairs to boost AOV (average order value).

- L.A.-made speed to shelf: Local production means no 6-month waits for imports. Restock bestsellers in weeks, not seasons—perfect for capitalizing on viral TikTok moments (#NudeButNotBoring).
