How to pick a swimsuit for an rectangle body
Sometimes finding the swimwear that actually fits your shape,not just your size is a real struggle. If you have a rectangle body shape and feel like most bikinis and one-pieces don’t ever fit you, find out you are not alone. From tops that feel too simple to bottoms that don’t define the waist, it’s easy to think your options are limited. The problem is not your body , you just have to find the design that flatters your shape instead of hiding it.
At Noire Swimwear, we design pieces that enhance your natural shape — not hide it.This guide is here to help you discover the best swimwear for rectangle body types — styles that work with your proportions to define the waist, add gentle curves, and make you feel beautifully confident in your own skin.
Understanding the Rectangle Body Type
A rectangle body type (sometimes called athletic, straight, or banana) is defined by:
- Shoulders, waist, and hips roughly the same width
- A less defined waistline
- Balanced proportions from top to bottom
- A generally lean, elongated frame
Your goal when shopping for swimwear?
To create curves and enhance dimension — especially around the bust and hips — while gently defining the waist.
Tops that flatter
Look for details and structure that add visual shape to your upper body.
- Padded or Push-Up Tops - Add gentle volume and curve to the bust area. Try our Underwire Top , Nikki Push-Up , Ruched Balconette for a feminine lift that still looks natural.
- Triangle Tops - A timeless cut that softens angles and adds a delicate balance. Adjustable ties let you customize your fit. Like our Coquillage Triangle Tops and Nikki Triangle Tops.
- Bandeau Tops - Effortless and sculpting, bandeau tops are a perfect match for rectangle body types. The clean, slightly curved neckline softens your natural lines while adding subtle shape to the bust.
Bottoms that flatter
Opt for bikini bottoms that emphasize the waist and enhance the curve of your hips.
- Cheeky or Brazilian Cuts - Playful and curve-enhancing, these cuts give your shape a feminine boost. Try our Brazilian Ruched or our Cheeky Ruched.
- High-Waisted Bottoms - Cinch your waist and add a hint of retro glam. The Coquillage High-Waist or Nikki High-Waist are perfect to create that hourglass illusion.
- Tie-Side -The delicate side ties draw attention to the hips and create the illusion of gentle curves, adding softness and shape to a straight silhouette.
One-Pieces that flatter
If you prefer a sleek one-piece, choose designs that sculpt and define your midsection.
- Belted or Cut-Out One-Pieces - A belted waist or side cut-outs instantly add dimension, breaking up straight lines and emphasizing curves. Go for Coquillage Cut-Out One Piece or Seashell Balconette.
- Plunge Necklines or Halter Styles - Draw the eye upward and create a longer, more defined silhouette. Try our Ruched Halter One Piece or Sienna V One Piece.
