How to Measure Yourself
For an accurate Girlfriend Collective size, use a soft measuring tape and follow these steps. Measure whilst wearing minimal clothing and ensure the tape sits comfortably without compression:
- Bust: Measure at the fullest part of your bust wearing a non-padded and non-compressive bra (or no bra) with arms down and relaxed to your sides. The measuring tape should sit loosely around your chest without pulling or bunching.
- Waist: Measure your natural waist at the smallest part of your torso, usually where your body bends when you lean to the side. Keep the tape relaxed and parallel to the ground.
- Hips: Measure the fullest part of your bottom whilst wearing non-bulky bottoms. Stand with feet hip-width apart and ensure the tape is level all the way around.
- Inseam: Stand straight up with feet hip-width apart and measure from the centre of your crotch straight down to your ankle bone. This measurement is particularly useful if you're between sizes vertically.

Product-Specific Sizing Guidance
Signature Compressive Leggings
Girlfriend Collective's signature Compressive collection is designed to feel snug and tight on first wear. This is intentional and perfectly normal. With more wear and washing, the leggings will slightly relax and begin to mould to your body, providing a custom, supportive fit. Do not size up based on initial tightness — this fit is by design. If you prefer a more relaxed, less compressive feel, consider sizing up.
Sports Bras
Sports bras fit true to size across most of the Girlfriend Collective range. However, the Paloma Classic sports bra comes up slightly small, so we recommend sizing up in this style, especially if you are between sizes. If you fall between sizes in all other Girlfriend bras, data suggests they skew slightly towards the smaller side, so choosing the larger size is advisable.
Unitards & Dresses
For one-piece garments, we recommend taking the size you'd select in tops when choosing your unitard or dress size. If you have a longer torso and desire a more flexible, less compressive fit, sizing up by one size will provide additional length and comfort without sacrificing support.
Sizing Tips
- True to Size Fit: Girlfriend Collective garments are designed to fit true to your normal size. Always reference the detailed sizing chart specific to your chosen item type (bras, tops, bottoms, or one-pieces) for the most accurate fit.
- Compression is Key: The brand's signature compressive leggings are engineered to feel snug initially. This compression provides support and shaping. Initial tightness does not mean you've sized incorrectly. The fabric will relax slightly with wear and washing whilst maintaining its supportive properties.
- Between Sizes Strategy: If your measurements fall between two size categories, decide what fit experience you prefer. Size down for a more compressive, body-hugging feel, or size up for a more relaxed, flexible fit that's still supportive.
- Measure Multiple Times: For the most accurate sizing, measure yourself on different occasions throughout the day, as body measurements can vary slightly depending on hydration, time of day, and clothing worn. Take an average of your measurements if they vary.
- Account for Torso Length: If you have a particularly long or short torso, this affects how one-piece garments fit. The inseam measurement is particularly important for unitards and dresses. Reference the dedicated one-piece size chart and consider sizing up if you have a longer torso and want a less compressive fit.
- Customer Service Support: If you remain uncertain after measuring and consulting the size charts, Girlfriend Collective's team are available to help. Email [email protected] with your measurements and a description of the item you're interested in, and they'll provide expert sizing recommendations tailored to your specific needs.
- Non-Bulky Bottoms When Measuring: When measuring your hip circumference, wear non-bulky bottoms such as leggings or slim trousers. Thick, padded, or loose-fitting bottoms can distort your hip measurement and result in an incorrect size selection.
- Soft Measuring Tape Essential: Use only a soft, flexible measuring tape — not a rigid ruler or hard tape measure. A soft tape sits naturally against your body without bunching or adding extra width to your measurements, ensuring accuracy.
- Relaxed Body Position: Always measure with relaxed arms at your sides and whilst standing in a natural, comfortable position. Do not flex your muscles or pull your tape tight. A snug but not compressive tape position gives the most realistic measurements that match Girlfriend Collective's sizing.
Frequently Asked Questions
Are Girlfriend Collective garments true to size?
Yes, Girlfriend Collective aims for all garments to fit true to your normal size. However, like all brands, there are slight variations between pieces. Always consult the specific size chart for the item you're interested in and measure carefully for the best fit.
What if I'm between sizes?
If your measurements fall between two sizes, consider your preferred fit. Size down for a more compressive, supportive feel, or size up for greater comfort and flexibility. The choice depends on your personal preference and the intended use of the garment.
Why do my leggings feel so snug initially?
Girlfriend Collective's signature Compressive leggings are designed to feel tight and supportive when new. This compression is intentional and helps shape and support your body during activity. The fabric will relax slightly over time and with washing whilst maintaining its supportive qualities. Do not be alarmed by the initial snug fit.
Do I need to size up for the Paloma Classic sports bra?
Yes, the Paloma Classic comes up slightly small compared to other Girlfriend Collective bras. We recommend sizing up in this specific style, particularly if you find yourself between two standard sizes.
How should I size unitards if I have a longer torso?
Generally, select the size you'd wear in tops for unitards and dresses. If you have a longer torso and prefer a less compressive, more flexible fit, sizing up by one size will provide additional length and comfort without compromising support.
What's the best way to ensure an accurate measurement?
Use a soft measuring tape and measure at different times throughout the day if possible. Wear non-bulky clothing and keep your body relaxed. Measure the fullest parts of your bust, waist, and hips without pulling the tape tight. If measurements vary, take an average.
How long do returns and exchanges take?
Girlfriend Collective offers hassle-free returns and exchanges within 30 days of purchase for UK and US customers. If an item doesn't fit as expected, you can exchange it for a different size at no additional cost.
