Monday Swimwear vs Andie Swim: Which Is Worth It?

Monday Swimwear and Andie Swim both sell direct-to-consumer suits with sustainability credentials and strong reviews, but they solve different problems. Monday is the better pick if you have a large cup relative to your band or want elevated resort styling, thanks to its P–VVV fit range and 82% recycled-nylon hand. Andie wins on price and flexibility, with suits starting around $52, a straightforward XS–3X range, and the ability to choose your coverage and torso length on many styles.

Prices and policies below reflect each brand’s listings as of early 2026 and shift with seasonal drops and sales, so confirm current figures on each site before buying. Here is a category-by-category breakdown, with an honest winner called for each.

Fit and sizing

Monday is built around the bust. The brand uses its own P–VVV sizing system that runs from Petite up through V, VV, and VVV (Voluptuous to Very Very Voluptuous), with cup ranges spanning A to G on many tops. It also runs a dedicated small-band, large-cup collection fitting 28E through 34DD, which is unusual in DTC swim. One reviewer who wears a size 12 and a 36G reported that even Monday’s underwire tops fit her cup, and that she keeps returning to the brand after trying dozens of others.

Andie takes a different route. It uses standard alpha sizing (XS through 3X) and competes on adjustability rather than cup-specific engineering. Where Andie pulls ahead is torso length: many styles come in a dedicated long torso version, which is genuinely hard to find and matters if standard one-pieces cut into your shoulders or ride high. Andie also offers maternity-friendly and mastectomy-friendly options on select suits.

Winner: Tie. If your fit challenge is a full bust or a small band with a large cup, Monday is the clear answer. If it’s a long torso or you want a suit that adjusts across coverage without cup math, Andie fits better. They win for different bodies.

Size inclusivity

On paper the two brands land in a similar place. Andie’s alpha range tops out at 3X (XXXL), and Monday’s system stretches to VVV with A–G cups, so both cover a comparable spread of bodies. The difference is how they get there.

Monday’s range is depth-first: it goes deep on bust and band combinations rather than wide on general body size. Andie’s is breadth-first, offering one coverage-and-length grid that most shoppers can navigate without knowing their cup size. Neither brand offers extended plus sizing beyond roughly a 3X-equivalent, so shoppers above that range will be limited with either.

Winner: Andie, by a narrow margin. Its XS–3X grid plus long-torso and coverage variants is easier to shop for the average customer, even though Monday goes deeper for full-bust bodies specifically.

Fabric and quality

Monday’s suits are cut from a heavier 82% recycled nylon and 18% spandex jersey, confirmed on product pages like the Clovelly One Piece and Bordeaux. The fabric has a dense, smoothing hand that reviewers tie to the brand’s support reputation, and care is hand wash cold, lay flat to dry. That density is part of why the suits cost what they do.

Andie’s Eco Nylon is also a recycled-content fabric. Independent testing by Treeline Review found Andie’s Maui top holds up over years of lake, pool, and ocean use with no pinching or sagging, and rated its cheeky bottoms as the best plus-size two-piece bottom for durability. The fabric leans lighter and sportier than Monday’s.

Winner: Monday, narrowly. Both use recycled fabrics and both hold up, but Monday’s heavier jersey delivers more built-in shaping and support, which is the harder thing to engineer.

Styles and coverage

This is where the brands diverge most clearly. Monday leans into a curated, resort-forward aesthetic: neutral palettes, crinkle and textured fabrics, matching cover-ups and sarongs, and silhouettes designed to photograph well on vacation. You choose a style, and the coverage comes with it.

Andie flips that. On many styles you pick your seat coverage (cheeky, medium, or full) and often your torso length, so the same suit adapts to what you want. That modularity is Andie’s signature and a real advantage if you like full coverage on the bottom but a minimal top, or vice versa.

Winner: Andie for flexibility, though this one is close to a matter of taste. If you want to dial in coverage, Andie gives you the levers. If you want a designed, resort-ready look without decisions, Monday delivers that.

Price and value

Andie is meaningfully cheaper. At the time of writing, its separates start around $52 for a cheeky bottom and $62 for the Maui top, with one-pieces roughly $95 to $148. Monday’s tops sit around $104 to $107 and its one-pieces run to roughly $189 to $197, so a full Monday two-piece set often costs more than a complete Andie one-piece.

Whether Monday earns the premium depends on your fit needs. For a full-bust shopper who struggles to find supportive tops elsewhere, the extra cost buys a fit that’s hard to replicate. For a shopper with a standard fit who mainly wants a good-looking, durable suit, Andie delivers most of the value for far less.

Winner: Andie. On pure cost and cost-per-suit, it’s not close.

Sustainability

Both brands build recycled nylon into their core fabrics rather than treating it as a limited capsule. Monday states its jersey is made largely from recycled nylon yarns reclaimed from production scraps, and applies it across the line. Andie’s Eco Nylon runs through many of its bestsellers, including the Amalfi one-piece, and the brand markets sustainability as a standing commitment rather than a one-off.

Neither publishes the kind of detailed third-party impact reporting that specialist eco brands like Vitamin A do, so treat both as solid mainstream efforts rather than sustainability leaders.

Winner: Tie. Both use recycled-content fabric widely and neither clearly out-documents the other.

Shipping and returns

Andie offers free U.S. shipping on orders over $150 and free exchanges on U.S. orders, which lowers the risk of buying the wrong size in a fit-sensitive category.

Monday’s policy is tighter. U.S. customers can return unworn items with tags and liners for a refund, store credit, or a one-time exchange, and the brand deducts a returns processing fee and does not refund shipping, according to a review of the policy. International returns are refund-only, with no exchanges or store credit, per Monday’s refund policy. Return terms change, so check the current policy pages before ordering; if you’re outside the U.S. and unsure of your size, that gap is worth factoring in.

Winner: Andie, mainly for the free U.S. exchanges, which matter more than usual when you’re guessing at fit.

Who should choose Monday

Choose Monday if support and a full-bust fit come first. If you wear a D through G cup, need a small band with a large cup, or have struggled to find a bikini top that actually holds you, Monday’s P–VVV system and heavier recycled jersey are worth the higher price. It’s also the stronger pick if you want a coordinated, resort-ready look with matching cover-ups and a polished, neutral aesthetic.

Who should choose Andie

Choose Andie if you want flexibility and value. Its XS–3X sizing, choose-your-coverage options, and dedicated long-torso styles let you tailor a suit to your body without cup-specific fitting, and the prices run well below Monday’s. Free U.S. exchanges make it lower-risk to try. It’s the better fit for shoppers with a standard bust who prize adjustability and a sportier, everyday feel.

Final verdict

These are both strong DTC swim brands, and the right answer depends on your fit and budget, not on which is objectively “better.” Monday wins on full-bust engineering, fabric weight, and elevated styling. Andie wins on price, coverage flexibility, long-torso options, and easier returns. Size inclusivity is close, and both are comparable on sustainability.

If your fit challenge is your bust, pay more and go with Monday. If it’s your torso length, your budget, or you simply want to fine-tune your coverage, Andie is the smarter buy. Neither will disappoint the shopper it’s built for.
