Side Tie
Side Tie
A closure system using ties at the sides of underwear or bikini bottoms, allowing adjustable fit and easy removal.
What Is a Side Tie?
A side tie replaces the traditional sewn side seam of underwear or bikini bottoms with ribbons, strings, or fabric strips that tie into bows at each hip. This converts a fixed-size garment into an adjustable one — the wearer controls the fit by tying tighter or looser, and the bottom can be removed by simply pulling one end of each bow.
Side ties matter for two reasons. Practically, they solve sizing uncertainty: hip measurements vary widely, and a tie closure accommodates 5-8 cm of variation in a single size, making these bottoms far more forgiving than elastic-waist designs. Aesthetically, the bows draw attention to the hip line, creating a playful visual accent that turns a simple bottom into a statement piece.
Quality side ties use double-layer ribbon or woven fabric strips that hold a knot securely without slipping. The attachment point where the tie meets the garment body should be bartacked or reinforced — a common failure point in cheap versions is the tie pulling free under tension. The tie length should be generous enough (20-25 cm per side) to allow a proper bow with tails, not just a basic knot.
Sinderella uses side-tie closures across lingerie sets and swimwear, pairing satin ribbon ties with lace or mesh body panels. The adjustable fit makes these pieces among the most popular gift items in the collection.
How to Wear & Style
Side-tie bottoms pair naturally with matching bralettes or bra tops for a coordinated set. For lounging, tie them loosely with long trailing bows for a relaxed look. For a sleeker line under a sheer robe or coverup, pull the ties snug and tuck the ends flat. When gifting, side-tie pieces are one of the safest choices because the adjustable closure greatly reduces the risk of a wrong-size purchase.

Are side-tie bottoms practical for everyday wear?
Side-tie bottoms are designed more for bedroom, lounge, or swim settings than for daily wear under clothing. The bows can create visible bumps under fitted trousers or skirts. However, flat-knotted side ties with short ribbon ends sit flush enough for wear under looser garments like dresses or skirts.
Why are side-tie bottoms a popular lingerie gift?
Because the ties adjust to a wide range of hip measurements, making exact sizing less critical. A side-tie bottom in size M can often fit someone who normally wears S or L by simply tying tighter or looser. This adjustability, combined with the playful unwrapping element, makes them one of the most-gifted lingerie bottom styles.
