10 Eco-Friendly Plus-Size Swimwear Brands Under $50

I’m a serial cannon-baller. If a suit shifts, rolls, or flashes mid-splash, it’s out. Last summer I decided I also wanted my pool days to be kinder to the planet and my wallet. That meant one clear target phrase in every search bar: eco friendly plus size swimwear under 50. Turns out the niche is still under-served, so I grabbed ten suits that met three rules:

• Price tag ≤ $50 (regular price or a sale that comes around often)
• Sizes to at least 3X (many reach 4X or 24W)
• A real sustainability angle,recycled fabrics, low-impact dyes, or circular resale

I paid for five of these myself and borrowed the rest from friends or clothing-swap groups. Then I hit the city pool, lakeside dock, and a pretty sketchy hotel slide (all in the name of research). Here’s who survived the dive.

How I Picked Them

1. Price ceiling – Anything over fifty bucks stayed on the wish-list.
2. Eco filter – Look for ECONYL®, REPREVE®, dead-stock fabrics, or certified dyes.
3. Size range – XL is a start, but 3X is the minimum for real inclusion.
4. Jump test – Two cannon-balls and a glide down a slide; no strap failures allowed.

Quick Fabric Primer

Recycled nylon feels and stretches like new nylon because it is nylon,just spun from old fishing nets or carpet. Chlorine, salt, and sun treat it the same, so durability isn’t the trade-off people fear. Look for double-lining in the front panel; recycled fabrics can be a hair thinner.

Buyer’s Checklist

• Measure torso length; a longline top can handle extra height.
• Double-lined fronts matter,lighter recycled fabrics can go sheer.
• Scan fiber tags for ECONYL® or REPREVE®.
• Keep receipts; stretch relaxes after one swim, and you may need to size down.

Caring for Recycled Suits

1. Rinse in cool tap water right after a dip.
2. Skip hot dryers,heat breaks elastane.
3. Use a micro-filter laundry bag to trap loose fibers.
4. Flat-dry in shade; direct sun fades prints faster.
