Quick answer
Choose a tie back cover up by matching the bust measurement to your body, not by guessing from your usual dress size. If you want adjustable coverage, look for ties at the back or shoulders; if you want a fixed, clean line, choose a pull-on style. For a hollow out cover up, size up if you plan to wear it over a wet swimsuit because the open weave can cling.
Measure your bust, not your dress size
Cover-ups sit over a swimsuit, so your bust measurement is the number that matters most. Use a soft tape measure around the fullest part of your bust, keeping it level. If you are between sizes, go with the larger size for a tie back style because the ties let you cinch in excess fabric, but you cannot add fabric where it is too tight. For a hollow out cover up, the open pattern has less stretch than a solid knit, so the bust measurement becomes even more important. The Crazy For You Cover Up lists bust measurements for each size: XS is 33.9 in, S is 35.4 in, M is 37 in, and L is 39.4 in. That gives you a concrete starting point instead of relying on S/M/L labels alone.
Decide where you want the ties to sit
Tie back cover-ups usually have ties at the center back, the shoulders, or both. Center-back ties create a defined waist and work well if you want shape without a belt. Shoulder ties let you adjust the neckline and strap drop, which is useful if you have a longer or shorter torso. If the ties are only at the back, the front neckline is fixed, so check the product photos for how low it sits. A cover up for swimwear that ties at the shoulder gives you more control over coverage across the chest. If you prefer zero adjusting, a pull-on style is simpler, but you lose the custom fit.
Match the cover-up length to your height and plans
Length affects how versatile the cover-up is. A shorter cover-up that ends at the hip works over a bikini for a beach walk or poolside lunch. A longer style that reaches mid-thigh or below gives more coverage for resort dining or sightseeing. Check the length measurement in the product details rather than judging from the model photo. The Crazy For You Cover Up lists length by size: 23.2 in for XS, 24 in for S, 24.8 in for M, and the L measurement is listed in the catalog. If you are tall, a cover-up under 25 in will sit higher on the thigh than it does on a shorter frame. If you are petite, a longer cover-up may read as a dress, which can be a bonus or a drawback depending on where you are wearing it.
Understand what a hollow out cover up does differently
A hollow out cover up uses an open, patterned knit or crochet-style fabric. It looks more textured and lets more air through, which is helpful in heat. The tradeoff is that it offers less opacity than a solid fabric, so you will see your swimsuit through it. That is usually the point, but it means the swimsuit becomes part of the outfit. If you want more coverage, choose a solid cover-up or layer the hollow out style over a solid bikini rather than a high-contrast print. Also check the care instructions: open weaves can snag on rough surfaces, so keep them away from velcro and jagged pool edges.

Check the return window before you commit
Fit is personal, and a tie back cover up that looks right on the model may sit differently on you. Before ordering, confirm the store's return policy for swimwear and cover-ups. Some retailers require tags to be attached and limit returns on items worn near water. If you are ordering a size you are unsure about, keep the packaging and tags intact until you have tried it on over your actual swimsuit, not your everyday underwear. That way you can compare the bust and length measurements against your own body before deciding.
Decision rules for tie back cover-ups
- If your bust measures between two sizes: Choose the larger size. Tie back styles can be cinched in at the back or shoulders, but they cannot be let out. Size up for adjustable coverage.
- If you want a defined waist: Look for a center-back tie. It pulls the fabric in at the narrowest part of your torso without needing a separate belt. Center-back ties create shape.
- If you are wearing it over a wet swimsuit: A hollow out cover up can cling when damp. Size up or choose a solid fabric if you want it to drape away from the body. Open weaves cling more when wet.
- If you are tall or have a long torso: Check the length measurement. A cover-up under 25 in will sit higher on you than it does on a shorter frame. Length matters more than the size label.
- If you want zero adjusting: Skip tie back styles and choose a pull-on cover-up. You trade custom fit for simplicity. Ties mean adjustability, not effortlessness.
Product facts to guide your choice

Bust measurements are listed as 33.9 in (XS), 35.4 in (S), 37 in (M), and 39.4 in (L). Length measurements are 23.2 in (XS), 24 in (S), and 24.8 in (M). These measurements let you compare your own bust and preferred length before ordering, which is more reliable than choosing by dress size alone.
- Love Me More Bandeau Bikini: The Love Me More Bandeau Bikini lists separate top and bottom measurements. Top bust measurements range from 25.6 in (S) to 31.1 in (XL), and bottom waist measurements range from 25.2 in (S) to 30.7 in (XL). If you are choosing a cover-up to wear over this bikini, you can match the cover-up bust measurement to the bikini top size for a consistent fit.
- Curve Tattoo Bralette: The Curve Tattoo Bralette lists cup fit by size range: 1XL/2XL fits sizes 14-18 with a bust of 42 in to 46 in, and 2XL/3XL fits sizes 20-24 with a bust of 48 in to 52 in.
