In April 2026, WWD covered the first New York flagship of Monday Swimwear at 464 Broome Street in SoHo. It is a full-circle address: founders Natasha Oakley and Devin Brugman named the brand in a New York taxi in 2013, around the idea that wearing a bikini on Monday meant you were having a good day. I like a founding story that starts with a mood and ends with an actual door.

Before storefronts, there was A Bikini A Day. Oakley says she and Brugman founded the blog in 2012 and shared a different bikini each day. Talking with women about support, hip fit and feeling at ease exposed a gap; their response was to launch Monday in 2014. WWD notes that the label accommodates cup sizes AA through G after Brugman had struggled to find swim options for her E/F cup size. That origin gives the details here a purpose. Adjustability is not an afterthought.

The tops move from spare to structured. The Acapulco Top in black is a slim strap triangle with a tie back and gold hardware; the Capri Top brings underwire to deep burgundy crinkle. Petit Ermitage’s Milano stripe puts gold at the front with over-shoulder straps, while the ivory Taormina has removable pads and adjustable neck and back ties. For more structure through the shoulder, Cala Roja’s floral U-wire shape has wider straps, and the blue gingham Sorrento comes with demi underwire.

I would decide by shape and adjustments, then think about color: check that the back tie has room to move, that each strap slider gives enough range, and whether I want removable padding. Black or stripe is a straightforward base for a suitcase; the floral has a little more to say without turning the top into a costume.

WWD describes this label as size inclusive and says fit sits at the center of its design, with cup sizes AA through G. For bottoms, I would begin with waist height and coverage, then check the side details. A print is the fun part, not the measuring tape.

The Seychelles Bottom in Milano stripe is mid-rise with moderate coverage; the Petit Ermitage Bottom uses fine sides, gold hardware and minimal thong coverage. For more coverage in the same stripe family, the Sydney Short is low-rise with a gold hardware belt and no center front or back seam. Deep burgundy crinkle gives two different options: the Byron Bottom is mid-rise with cheeky coverage, while the Palma Thong has adjustable side ties.

The Cannes Bottom has a floral print, adjustable sides and gold rings. The St. Lucia Bottom adds a V front and high leg, while the Formentera Bottom pairs its high waist with a cheeky cut. I would wear the Sydney Short with a roomy button-down for lunch, or keep a matching print for a deliberate set. Before choosing, bend and sit in the size you are considering, then check whether the side ties stay where you want them. What I would skip: choosing a minimal side solely because its print looks good on the product page. Coverage and tie placement come first.

A plunging neckline is only one part of a one-piece’s story; the back, leg cut and waist detail do just as much work. Clovelly One Piece has underwire cups and an open back with a tie closure. Ravello stays in deep burgundy crinkle with a wide V, while Croatia brings a halter plunge in Monte Solaro floral.

Cyprus repeats the halter and low back in chili pepper crinkle. For a higher neckline, Bahamas has a rounded neck and built-in bra with removable padding; Florence adds an espresso tone and pleated waist. Bordeaux is the midnight option with a crossover neckline and full-coverage leg. Montego’s white rib and center-front ring make it the more graphic pick, especially beside the softer shape of Ravello.

I would style a high-leg suit with a loose shirt or a wrap skirt, and let a lower leg line do the quieter work under trousers. The construction is the useful part to compare: underwire and open back on Clovelly, built-in bra and removable padding on Bahamas, adjustable straps on Florence.

Before deciding, I would check torso length, strap adjustment and how much back exposure I actually want. A suit can be adjustable up top and still need to sit comfortably through the body, so I would treat those as separate questions rather than letting the neckline make the whole decision.

WWD described the SoHo flagship as a quiet retreat in a historic cast-iron building. I like that as a useful way to think about a cover-up: not a disguise, just the layer that lets a beach day expand by a few hours.

St. Barth’s Skirt is a short Milano stripe wrap with a tie and semi-sheer finish. St. Tropez Sarong uses deep burgundy cotton voile and a raw edge; La Jolla Shirt is striped, with a collar, buttons, chest pocket and long sleeves, still semi-sheer. Dominica Poncho shifts the line into a deep burgundy asymmetrical off-shoulder knit. When I want more length, St. Croix Maxi Skirt has a twisted draped waist and mesh lining, while Palermo Skirt is sheer crochet with a side slit and gold ring.

The pieces ask for different amounts of coverage: a sarong keeps the leg line visible, a shirt covers the arms, and a lined maxi moves toward late dinner. I would check opacity near a window, then tie a wrap and walk a few steps to see whether it stays where I want it. What I would skip: relying on a listing photo to answer how sheer a layer is, especially if the plan runs from the water to a restaurant. I would consider lining and pack a simple slip if the layer needs it.

WWD sees the offer extending from bikinis and one-pieces into matching cover-ups and resortwear. I like that progression, because the useful vacation wardrobe is not an extra dress tossed in at the last minute. It is a few layers that can move from salty hair to the table without turning into a packing puzzle.

Marabella Kaftan is a black tissue-jersey maxi with long sleeves, a V neck and front ties. Montego Halter Dress is deep burgundy lace crochet with a gold ring, keyhole and side slit, and it is fully lined. Santorini Kaftan brings ivory lace crochet, a plunging neck and a semi-sheer long-sleeve shape. Provence Dress uses deep burgundy mesh with a square neck and center-back slit; Waikiki Mini Dress is the shorter lace option with a scoop neck and tie halter.

For separates, Belize Pant has Milano stripe silk and an adjustable drawstring waist, while Casablanca Pant is midnight linen with pockets and belt loops. Galapagos Sweater is ivory open knit, one-shouldered, with a wraparound waist tie. I would check the lining in daylight, see where the waist tie lands, and walk a few steps to judge the slit. What I would skip: packing three layers with the same job. I would choose one sheer piece, one opaque piece and one that can handle evening air.

I would pack in this order: choose the suit around the coverage I want, add one wrap or shirt for the hours between water and dinner, then finish with a dress or trouser that can leave the pool. The label’s story makes that order feel earned. Oakley and Brugman began with A Bikini A Day, then built a swim line after hearing what women needed from a suit. WWD’s account of the SoHo opening returns the story to the city where the name began.

That New York taxi brainstorm turned a Monday into a small vacation premise. I would leave enough room in the bag for the day to change its mind. If you want to keep browsing, I also put together Bikini Sets And Halter Tops and JUILLET SWIMWEAR.
