How to Choose the Right Undie Style for Your Body

Quick answer

Choose your undie style by coverage first, then by elastic placement and fabric. If you want full coverage with a soft outside elastic, pick Big Knickers or Very Big Knickers. If you prefer a simple everyday brief, pick Regular Briefs. If you want a side split and zero post-consumer waste, pick The Very Good Bra Briefs. If you want a soft Tencel 3-pack, pick The Very Good Undies - 3 Pack of Black.

Most underwear advice tells you to "find your body type" and then hands you a vague diagram. That is not helpful when you are standing in front of a drawer deciding what to buy. The real decision comes down to three physical things: how much coverage you want, where the elastic sits, and what the fabric does against your skin.

This undie styles guide walks through the cuts and fabrics in The Very Good Bra range so you can choose underwear style that fits your daily life, not a label. Every option here is designed to break down at end-of-life, but they are not interchangeable. The differences in coverage, elastic placement, and fiber content change how they feel and how they wear.

Start with coverage, not body type

Coverage is the fastest way to narrow the field. A high-leg or side-split brief leaves more skin exposed at the hip, which can feel cooler and more minimal. A full-coverage brief covers more of the seat and upper thigh, which reduces rubbing under dresses and skirts. Neither is better; they solve different problems.

If you have ever pulled at the back of your undies during the day, you likely need more coverage than you are wearing. If you feel fabric bunching under fitted trousers, you likely need less coverage or a smoother edge. Use your own past discomfort as the signal, not a body-type chart.

• High-leg or side-split cuts suit fitted trousers and warm weather.
• Full-coverage cuts suit dresses, skirts, and long days on your feet.
• If you are between two sizes, size up for coverage and down for a closer fit.

Elastic placement changes everything

Where the elastic sits is the most underrated fit detail. Some briefs have elastic encased or sewn on the outside of the cotton body. That outside placement keeps the elastic from pressing directly against your skin, which many people find more comfortable, especially if you are sensitive to pressure or heat.

Other styles have soft leg elastic to hold the brief close. That can be helpful if you want a secure feel under activewear or if you dislike any shifting. The trade-off is that more elastic contact can feel less airy. Match the elastic design to how much movement you expect during the day.

• Outside-sewn elastic reduces direct skin contact and pressure points.
• Soft leg elastic adds security but slightly less breathability.
• Check the waistband width: 6mm is a common comfortable middle ground.

Fabric choices: organic cotton vs Tencel

Organic cotton is breathable, durable, and familiar against the skin. It handles repeated washing well and works for most people most of the time. Tencel is smoother and drapes more softly, which can feel cooler and more luxurious, but it has a different hand feel and may show wear differently over time.

Both can be plastic-free. The key is to check the elastic, sewing thread, and labeling, not just the body fabric. A garment is only as plastic-free as its smallest component. If a product page does not list those details, treat that as a gap in information and ask before you buy.

• Choose organic cotton for everyday durability and a matte finish.
• Choose Tencel for a smoother, cooler feel under lightweight clothing.
• Confirm elastic, thread, and labels are plastic-free, not just the main fabric.

Match the cut to your outfit, not just your body

The undie you wear under a summer dress is not the one you wear under leggings. A full-coverage brief with outside elastic can be ideal under a dress because it stays put and reduces chafing. A simpler brief with less coverage can be better under fitted trousers where you want fewer lines and less fabric.

Think about your week: how many days are you in dresses, how many in trousers, how many in loungewear? Buy for the majority, then add one or two styles for the outliers. A small, intentional rotation beats a drawer full of almost-right options.

• Dresses and skirts: prioritize coverage and stay-put elastic.
• Fitted trousers: prioritize smooth edges and minimal bulk.
• Loungewear and sleep: prioritize softness and breathability.

Decision rules for choosing your undie style

• If you want full coverage with no digging: Choose Very Big Knickers - Ecru or Big Knickers - Black Tencel. Both are designed for more coverage, and the outside-sewn elastic on the Ecru keeps pressure off your skin. Best for dresses, long days, and anyone who hates adjusting.
• If you want a simple everyday brief: Choose Regular Briefs - Latte. It is 100% organic cotton with outside-sewn 6mm elastic, no boy-legs or cheeky cuts. Best for a no-fuss drawer staple that works under most outfits.
• If you want a higher-leg, lighter feel: Choose The Very Good Bra Briefs - Vintage Peach. The cuff and side split give more airflow and a higher leg line, and every component is designed to break down at end-of-life. Best for warm weather and fitted trousers where you want less fabric.
• If you want to refresh your drawer in one purchase: Choose The Very Good Undies - 3 Pack of Black. Three pairs in Lenzing Tencel with 100% plastic-free elastic and thread, and OEKO TEX pad-print labeling. Best for value and for trying Tencel without committing to a single pair.

Product facts that affect your choice

• Very Big Knickers - Ecru: Super-sized for Big-Knicker lovers who found the first ones skimpy, in soft unbleached and undyed organic cotton with no spandex, and 6mm tree-rubber and organic cotton elastic sewn on the outside. If you want maximum coverage and minimal skin contact from elastic, this is the most generous cut here. The outside elastic is a real comfort feature, not a marketing line.
• Regular Briefs - Latte: A basic regular cotton brief in 100% organic cotton, with 6mm tree-rubber and organic cotton elastic sewn on the outside for extra comfort. This is the straightforward everyday choice if you do not want boy-legs, cheeky cuts, or extra coverage. The outside elastic keeps pressure off your skin.
• The Very Good Bra Briefs - Vintage Peach: The original brief with cuff and side split, made in premium organic cotton knitted and ACO dyed in Australia, zero post-consumer waste, with every component designed to break down in nature at end-of-life. The side split gives a higher-leg look and more airflow. If you want a lighter feel and a verified plastic-free build, this is the one to try.
• The Very Good Undies - 3 Pack of Black: A 3 pack of everyday undies in black made in premium Lenzing Tencel, knitted and GOTs dyed in Australia, with elastic and sewing threads 100% plastic-free and pad-print labeling using OEKO TEX inks. This is the value and fabric alternative: three pairs, Tencel softness, and a fully plastic-free component list. Good if you want to refresh your drawer in one go.
