The best starting point for a plus-size boho dress is the room you need and the way you want the fabric to fall. A shirred waist creates a different outline from a loose kaftan. Neither belongs to one body shape: the garment’s measurements, length and comfort are more useful than a rigid styling rule.
1. Use body-shape guides as a starting point
Pear, inverted triangle, apple, rectangle and hourglass describe proportions. They do not tell you which parts of your body to show or hide. Decide whether you want definition at the waist, more space around the middle or a skirt that moves freely over the hips.
If your hips are wider than your shoulders
A flared skirt or loose cut can give you room through the hips. Check the bust as well: a dress that fits comfortably below the waist may still feel tight higher up. A detailed neckline or full sleeve is a styling option, not something you need to “balance” your body.
If your shoulders are wider than your hips
Look at the shoulder width, armholes and how easily you can raise your arms. You need not rule out flared sleeves. Notice where the fullness begins and how the fabric falls when your arms are relaxed.
If you want more room around your middle
A cut that falls freely from the upper body can offer an alternative to a fitted waist. Try sitting down as well as standing. If you enjoy wearing a belt, position it where it feels comfortable; an apple-shaped figure does not make belts off limits.
If your waist is straight or clearly defined
You can keep the line loose or choose shirring for a more defined waist. The elasticated area should move with you rather than press into your body. Equally, a defined waist does not oblige you to wear a fitted dress.
2. For waist definition: a shirred dress
This dress combines a long, flowing skirt with flared sleeves, a shirred waist and an adjustable lace-up V-neckline. The lacing changes the neckline opening; it does not replace choosing the right size.

The English product description lists one size for S–L and a plus-size cut for L–small XXL. The French listing gives 36–42 FR and 44–50 FR respectively. These are the brand’s guides for this particular dress, not universal US or UK size conversions. Compare your bust, waist and hip measurements with the chart, especially where letter sizes overlap.
The listed dress length is 146 cm. Its large coral leaf motifs on black also show why bold prints need not be excluded from a plus-size wardrobe. Choose the pattern you enjoy, then check the fit.
3. For a looser line: a turquoise kaftan
This turquoise kaftan offers a different construction if you prefer a dress without a shirred waist. A V-neckline, wide sleeves and side slits accompany its long, loose cut. Tasseled ties add a detail at the neckline.

The English listing gives one size for S–XXL, subject to the accompanying chart; the French page states 36–50 FR. “Loose” does not mean unlimited sizing. Check the body-measurement ranges and make sure the length suits how you plan to wear it.
The shirred dress and kaftan answer different preferences. One creates a point of definition at the waist; the other offers a freer line through the body within its stated measurements. Neither is automatically more flattering.
4. Judge length, fabric and print together
Short, midi and maxi dresses are not reserved for particular body shapes. Compare the listed length with a dress you already enjoy wearing, allowing for your height and chosen shoes. You should be able to walk, sit and use stairs comfortably.
Drape comes from the fabric and construction together. Both examples here are listed as sari silk with 70% silk and 30% rayon, also called viscose in the shop’s information. They are not pure-silk dresses. The FAQ explains that this is newly made fabric using recycled silk fibres, rather than garments cut from previously worn saris.
Look through several photographs before choosing a colour. Light and fabric batches can affect how shades appear, as the product pages explain. There is no compulsory print scale or colour palette for plus-size dressing. A large leaf print can be just as much your style as a small floral.
5. What to check before ordering
Look at the sizes offered on each page in the Dresses collection. Plus sizes sit within the existing collections; there is no separate plus-size collection you need to find to follow this guide.
- Compare bust, waist and hips with the chart for that exact model.
- Check whether figures refer to body or garment measurements.
- Read the length and shoulder details; ask for an important missing measurement.
- Check the fabric composition and care instructions.
- Select the intended size even if the main photograph shows another fit.
Sonja designs the garments and selects the fabrics. A partner workshop in Pushkar, India, makes the clothing. The shop does not offer made-to-measure clothing, but can help you choose among its existing sizes.
The FAQ separates the usual 2–3 working days of order preparation from transit time, which varies by destination. Return postage for a change of mind or an unsuitable fit is generally the customer’s responsibility, subject to applicable rules. Read the returns information before ordering.
Frequently asked questions
Should I size up for a boho dress?
Not automatically. The cut may already include the intended fullness. Use your measurements and the model’s chart rather than a general rule about sizing up.
Does a plus-size boho dress need a belt?
No. Belts and shirring change the shape, but a free-flowing cut is another option. Choose what feels comfortable and gives the look you want.
Can I wear a shorter dress or a large print?
Yes. Size does not determine the lengths or prints available to you. Check the fit, the coverage you prefer and how the dress moves.
Where are the plus-size options?
Within the regular collections, under the sizes and variants on each product page. Once you have chosen a cut, explore our six plus-size boho outfit ideas for ways to wear it.
